U.S President Barack Obama says he doesn't mind his daughter going on dates - as she has secret service protection.Talking to MTV, Obama was quizzed about whether he was more worried about Malia getting her driving licence, going out on a date, or using Facebook.He replied: "I'd worry about Facebook, right now. Only because - I know the folks at Facebook, they've revolutionised social networks - but Malia because she's well-known, I'm very keen on protecting her privacy."And he added: "Right now, even just for security reasons, she doesn't have a Facebook page."
