US Presidential candidates Donald Trump and Hillary Clinton argued about several key points that affect nearly everyone on the planet, from the threat of ISIS to nuclear proliferation.

The candidates made charges about each others' records while defending their own careers and policy proposals.

Fact-check #1: Trump claims he did not say global warming is hoax perpetrated by the Chinese.

Clinton: "Because we will be making investments where we can grow the economy. Take clean energy. Some country is going to be the clean energy superpower of the 21st century. Donald thinks that climate change is a hoax, perpetrated by the Chinese. I think it's real.”

Trump: "I did not. I did not. I do not say that. I do not say that."

Grade: False

Explanation: Trump tweeted in November 2012 that the "concept of global warming was created by and for the Chinese." This tweet resurfaced again in January 2016, when former Democratic candidate Bernie Sanders pointed it out on NBC's "Meet the Press." The next day, Trump addressed the comment on "Fox & Friends," saying his tweet was basically a joke: "I often joke that this is done for the benefit of the Chinese. Obviously, I joke. But this is done for the benefit of China, because China does not do anything to help climate change." Trump has, on other occasions between 2012 and 2015, called global warming a hoax, though he has not attributed it to the Chinese.

Fact-check #2: Clinton has been fighting ISIS her "entire adult life"

Trump: "See you are telling the enemy everything you want to do. No wonder you have been, no wonder you have been fighting ISIS your entire adult life."

Grade: False

Explanation: ISIS has its origins in Al Qaeda in Iraq, the Sunni insurgency group founded in 2004 after the U.S. invasion and occupation of Iraq. In 2013, the group re-branded itself as Islamic State in Iraq and al Sham (ISIS) and shifted operations to include Syria where the civil war enabled its growth and resurgence. This occurred after Clinton had finished serving as Secretary of State. Clinton is 68 years old and turned 18 in 1965, almost 51 years ago.

Fact-check #3: Trump started his business with $14 million borrowed from his father.

Clinton: "Donald was very fortunate in his life and that's all to his benefit. He started his business with $14 million, borrowed from his father, and he really believes that the more you help wealthy people, the better off we'll be and that everything will work out from there. I don't buy that. I have a different experience. My father was a small business man. He worked really hard."

Grade: Yes and No

Explanation: Trump claims that his business grew out of a $1 million loan from his father in 1975. But a casino license disclosure from 1985 shows that in the late 1970s and early 1980s Trump took $14 million in loans from his father and his father’s properties, according to the Wall Street Journal.

Fact-check #4: Trump said that Clinton called [the Trans Pacific Partnership] the "gold standard" of trade deals.

Trump: "You called it the gold standard. You called it the gold standard of trade deals. You said it’s the finest deal you have ever seen and then you heard what I said about it and all of a sudden you were against it."

Grade: Yes and no.

Explanation: Clinton said TPP "sets the gold standard,” and has used many other glowing terms to describe the agreement, but she did not say it was the "finest deal" she’s ever seen. While Clinton served as secretary of state, she promoted the TPP well after negotiations began in 2010, saying in 2012 in Australia that it "sets the gold standard in trade agreements to open free, transparent, fair trade, the kind of environment that has the rule of law and a level playing field.” She also used many other complimentary words, including "exciting," "innovative," "ambitious," "groundbreaking," "cutting-edge," "high-quality," and "high-standard,” according to a compilation by the fact-checking site Politifact – but there are no records of her saying it was "the greatest deal she’d ever seen.” Further, Clinton began to moderate her position on TPP as she began preparing her second presidential bid, culminating with a full renunciation of it during a 2015 PBS interview in which she said, "As of today, I am not in favor of what I have learned about it.” It is worth noting, however, that she was not serving as secretary of state when the deal was finalized. Clinton countered Trump in Monday’s debate by trying to clarify that she said she had "hoped” TPP would set a gold standard for trade. Clinton countered Trump in Monday’s debate by trying to clarify that she said she had "hoped” TPP would set a gold standard for trade. But it is clear from her 2012 remarks that, at least one time in public, she declared that it "set” the gold standard, with no qualifiers.

Fact-check #5: Trump says he has not suggested that he would negotiate down the national debt.

Clinton: "And when we talk about your business, you've taken business bankruptcy six times. There are a lot of great business people that have never taken bankruptcy once. You call yourself the king of debt, you talk about leverage, you even at one time suggested that you would try to negotiate down the --

Trump: "Wrong, wrong."

"National debt of the United States. Well, sometimes there's not a direct transfer of skills from business to government, but sometimes what happened in business would be really bad for government."

Grade: Yes and No

Explanation: Trump suggested he will renegotiate the national debt in an interview with CNBC on May 5, 2016, but then said in the Wall Street Journal on May 10, 2016 that he would buy back U.S. debt at a discount. "I’m only saying you can buy back…I’m saying if interest rates go up, you can buy debt at a discount on the market — just on the market. You just buy back debt on — at a discount," he told the Journal.

Fact-check #6: "Hillary Clinton also fought it" -- whether President Obama was a natural-born citizen, a key tenet of the "birther" movement.

Trump: "Well nobody was pressing it, nobody was caring much about it. I figured you'd ask the question tonight, of course. But nobody was caring much about it. But I was the one that got him to produce the birth certificate, and I think I did a good job. Secretary Clinton also fought it, I mean, you know -- now, everybody in mainstream is going to say, oh that's not true. Look, it's true."

Grade: False

Explanation: A Politico report has linked Hillary Clinton’s most ardent supporters to the circulation of an e-mail suggesting Obama was born in Kenya during the 2007-'08 campaign. But no evidence has ever been found connecting this claim with Clinton herself or her campaign. Since 2008, no fact checker or journalist has ever uncovered any evidence linking Hillary Clinton and her campaign to the start of the birther movement. An ABC News analysis found Trump tweeted 67 times about the birther movement, including after Obama released his birth certificate.

Fact-check #7: Trump on the Iraq war.

Trump: "I did not support the war in Iraq...I was against the war in Iraq."

Grade: False

Explanation: Trump expressed support for the invasion of Iraq before expressing some reservations.

Asked by Howard Stern on Sept. 11, 2002 if he was "for invading Iraq,” Trump at the time answered, "Yeah, I guess so.”

But by Jan. 28, 2003, Trump expressed some concern about the possibility of an invasion, telling Fox Business’ Neil Cavuto that President George W. Bush "has either got to do something or not do something, perhaps, because perhaps shouldn’t be doing it yet and perhaps we should be waiting for the United Nations, you know.” Then, on March 21, 2003, soon after the invasion of Iraq got underway, Trump told Cavuto that the war "looks like a tremendous success from a military standpoint.” While Trump now portrays himself as having been an outspoken opponent of the invasion, his public statements in the lead-up to the invasion tell a different story.

Fact-check #8: Clinton says Trump advocated for the actions the U.S. took in Libya.

Clinton: "He actually advocated for the actions we took in Libya. And urged that Gaddafi be taken out after actually doing some business with him one time."

Grade: Mostly True

Explanation: In a video posted on his YouTube video blog in February 2011, Trump did call for intervention in Libya. "It’s a carnage,” he said. "Now we should go in, we should stop this guy which would be very easy and very quick, we could do it surgically, and save these lives.” Later, Trump claimed never to have discussed Libya (false), and also claimed that he was in support of a surgical intervention only, killing Gaddafi only but not taking any other actions.

Fact-check #9: Trump said it was "wrong" that he had been "praiseworthy" of Russian President Vladimir Putin, as Hillary Clinton claimed.

Clinton: "There's no doubt now that Russia has used cyber attacks against all kinds of organizations in our country, and I am deeply concerned about this. I know Donald is very praiseworthy of Vladimir Putin."

Grade: False

Explanation: Trump has publicly said favorable things about Putin numerous times, usually while criticizing President Obama. In a GOP primary debate hosted by NBC News, Trump described his strategy for dealing with Putin as: "I would talk to him. I would get along with him." In a recent NBC forum, where the network also interviewed Clinton, Trump defended his comments pointing to strong domestic polling for Putin. When Putin authored an op-ed on Syria in the New York Times, in September 2013, Trump tweeted that it was a "masterpiece for Russia and a disaster for the U.S." Interviewed by MSNBC, Trump said of Putin, "He’s running his country, and at least he’s a leader, you know unlike what we have in this country."

Fact-check #10: Trump on crime rates.

Clinton: "Under the current [New York City] mayor, crime has continued to drop, including murders."

Trump: "You're wrong...Murders are up."

Grade: Mostly False

Explanation: New York City mayor Bill de Blasio was sworn into office on Jan. 1, 2014. Each of his first two years in office saw an overall drop in the seven major felony crimes, and so far this year major crimes are down nearly 3 percent compared to the same period last year. Murder statistics present a slightly more complicated picture during de Blasio's tenure. His first year in office saw 333 murders, two fewer than the year before. But his second year in office saw an uptick to 352 murders. So far this year, murders in New York City are down more than 4 percent than the same time period last year (246 murders through Sept. 18, 2016, versus 257 murders during the same time last year).

Fact-check #11: Clinton: Trump said "he didn't care" if Japan, South Korea and Saudi Arabia get nuclear weapons.

Clinton: "Of what we’ve heard Donald say has been about nuclear weapons, he has said repeatedly, that he didn't care if other nations got nuclear weapons, Japan, South Korea, even Saudi Arabia. It has been the policy of the United States, Democrats and Republicans, to do everything we could to reduce the proliferation of nuclear weapons. He even said, well, if there were a nuclear war in East Asia, well, you know, that's fine."

Trump: "Wrong."

Grade: Yes and No

Explanation: Donald Trump has said that America’s allies should pay more of their defense costs. Earlier this year Trump seemed to say that Japan might be better off if it had nuclear weapons to defend itself from North Korea. At a town hall in March he also seemed to support Saudi Arabia having nuclear weapons, but quickly corrected himself. In June, Trump denied that he wanted Japan to get nuclear weapons. Trump wants America’s allies to take more responsibility for their defense and has at times indicated it would be OK for Japan to have access to nuclear weapons to defend itself from North Korea.

Fact-check #12: Trump denies saying that pregnancy is an inconvenience to employers.

Clinton: "One thing Lester, he tried to switch from looks to stamina. But this is a man who has called women pigs, slobs and dogs. And someone who has said pregnancy is an inconvenience to employers."

Trump: I never said that."

Grade: False

Explanation: In fact, Trump said just that in an October 2004 interview with NBC's "Dateline." In the interview, Trump said pregnancy is "a wonderful thing for the woman, it's a wonderful thing for the husband, it's certainly an inconvenience for a business. And whether people want to say that or not, the fact is it is an inconvenience for a person that is running a business.”

Fact-check #13: Trump on stop-and-frisk.

Holt: "Stop-and-frisk was ruled unconstitutional in New York, because it largely singled out black and Hispanic young men -"

Trump: "No, you're wrong. It went before a judge who was a very against police judge. It was taken away from her and our mayor, our new mayor, refused to go forward with the case. They would have won an appeal. If you look at it, throughout the country, there are many places --"

Grade: Mostly False

Explanation: The moderator was correct. Stop and frisk was ruled unconstitutional by a federal judge in August 2013, a federal district court judge ruled the NYPD's stop-and-frisk tactics violated the constitutional rights of minorities, calling it a "policy of indirect racial profiling." Mayor Michael Bloomberg appealed the case. The Second Circuit Court would temporarily block the district judge's orders and removed her from the case, finding she had compromised "the appearance of impartiality surrounding this litigation.” But the court stopped short of overturning the district court’s ruling.

The stop-and-frisk program was still in the midst of the appeals process when newly-elected Mayor Bill de Blasio, who supported the district court ruling, settled the litigation and ended the controversial program.

Fact-check #14: Trump says stop and frisk works "well."

Trump: "Over 4 -- almost 4,000 people in Chicago have been killed. We have to bring back law and order. Now, whether or not in a place like Chicago, you do stop and frisk, which worked very well, [former New York] Mayor Giuliani is here, it worked very well in New York. It brought the crime rate way down, but you take the gun away from criminals that shouldn't be having it."

Grade: Yes and No

Explanation: There has been much debate about whether stop-and-frisk is effective. Trump often cites the example of the tactic being used by police in New York City, as he did this evening. While violent crime fell in New York City while stop and frisk was implemented, the crime rate also fell nationally and in places where police did not employ the tactic. Stop-and-frisk may have some limited impact, but it is not clear how effective it is. According to NYCLU data guns were recovered in only .2 percent of cases.

According to an NYPD spokesman, the use of stop-and-frisk has decreased nearly 97 percent in New York City since 2011 while crime has decreased significantly during that same period. NYPD statistics bear this out.

Fact-check #15: Clinton claims Trump’s tax plan would add $5 trillion to the debt and cost the economy jobs.

Clinton: "Independent experts have looked at what I've proposed and looked at what Donald's proposed and basically, they've said this: That if his tax plan, which would blow up the debt by over $5 trillion and would in some instances disadvantage middle class families, compared to the wealthy, were to go into effect, we would lose 3.5 million jobs and maybe have another recession."

Grade: True

Explanation: Under Trump's current tax- and spending proposal, the debt over the next decade is projected increase by about $5 trillion, according to Moody's latest estimate. Another estimate from the Committee for a Responsible Budget says "both Clinton and Trump would increase the debt relative to current law – though Trump would increase it by an order of magnitude more, and Clinton’s plan would slightly reduce deficits if we incorporated unspecified revenue from business tax reform. Specifically, we estimate Clinton’s plans would add $200 billion to the debt over the next decade, while Trump’s plans would add $5.3 trillion.

Fact-check #16: Trump on the DNC being hacked.

Trump: "I don't know if anyone knows it was Russia that broke into the DNC. She’s saying Russia, Russia, Russia, but I don’t -- maybe it was. I mean, it could be Russia, but it could also be China. Could also be lots of other people. It also could be somebody sitting on their bed that weighs 400 pounds, okay? You don’t know who broke into DNC.”

Grade: Mostly False

Explanation: U.S. officials –- speaking on the condition of anonymity due to the sensitive nature of the information -– have uniformly told ABC News and other major news outlets that evidence in the DNC hack points directly to Russia. In addition, the firm hired by the DNC to respond to the suspected breach, CrowdStrike, conducted an investigation and later issued a statement saying it had "identified two sophisticated adversaries” as behind the hack. "Both adversaries engage in extensive political and economic espionage for the benefit of the government of the Russian Federation and are believed to be closely linked to the Russian government’s powerful and highly capable intelligence services,” CrowdStrike said. Just last week, the top Democrats on the House and Senate intelligence committees, Sen. Dianne Feinstein, D-Calif., and Rep. Adam Schiff, D-Calif., issued a statement saying, "Based on briefings we have received, we have concluded that the Russian intelligence agencies are making a serious and concerted effort to influence the U.S. election. At the least, this effort is intended to sow doubt about the security of our election and may well be intended to influence the outcomes of the election—we can see no other rationale for the behavior of the Russians.”

Fact-check #17: Trump says Ford is moving jobs out of the U.S.

Trump: "Ford is leaving. You see that. Their small car division, leaving. Thousands of jobs leaving Michigan, leaving Ohio, they're all leaving."

Grade: Mostly False

Explanation: Though Ford has announced it is moving production of the small Ford Focus to a new plant in Mexico, the company tells ABC the move will have "absolutely no impact on U.S. jobs.” While the new plant begins production of the Focus, workers at the Michigan plant (which was manufacturing the Focus) will instead make two new vehicles.
