Congressman Anthony Weiner is still fending off questions about an incident involving his Twitter account.

During a testy exchange in Washington yesterday, Weiner refused to directly answer questions about whether he sent the picture himself. He was questioned about why he hasn't asked law enforcement to investigate what was initially described as a hacking.

"If I was giving a speech to 45,000 people and someone in the back of the room threw a pie, or yelled out an insult, would I spend the next two hours responding to that? No. I would get back, I would get back," said Weiner.

Weiner yesterday also avoided saying he was "hacked" and instead called it a prank.

A picture was sent out under his name on Twitter showing a man in boxer briefs.

As with most Twitter content, it was visible to the public but was directed at one of his followers, a 21-year-old college student from Seattle.
