New York Republican Congressman Michael Grimm threatened to throw a reporter from NY1 over a balcony in the US Capitol, after the State of the Union address. The reporter had asked Grimm about campaign finance allegations.

A New York congressman apologized on Wednesday after being caught on television camera threatening to throw a reporter off a balcony and telling him, "I'll break you in half," after he was asked in an interview about a federal investigation into campaign finance violations.

Following President Barack Obama's  State of the Union address Tuesday night, Rep. Michael Grimm, a Republican from the New York City borough of Staten Island, was asked for his thoughts by New York 1's Michael Scotto.

After Grimm finished the interview, which took place on a balcony of the U.S. Capitol building, Scotto added, "And just finally before we let you go, since we have you here: We haven't had a chance to kind of talk about some of the..."

"I'm not speaking about anything that's off-topic," Grimm interrupted. "This is only about the president's speech tonight. Thank you."

Grimm, off-mic at that point, can be heard speaking to Scotto in a low voice.

Grimm says, "Let me be clear to you, you ever do that to me again I'll throw you off this f-----g balcony."

"Why?" Scotto says. "I just wanted to ask you..."

Grimm is heard again saying, "If you ever do that to me again..."

"Why? Why?" Scotto asks. "It’s a valid question."

After more [inaudible] talk Grimm says, "No, no, you're not man enough, you're not man enough. I'll break you in half. Like a boy."

Grimm then walks away.

On Wednesday, Grimm told reporters that his outburst had been wrong. Asked if he had been drinking, he laughed and said 'no', according to the interview which aired on NBC News.

"I'm a human being and sometimes your emotions get the better of you and the bottom line though is it shouldn't happen, you shouldn't lose your cool and that's why I apologized. When you're wrong, you're wrong, you have to admit it and it shouldn't have happened," Grimm told reporters, according to The Washington Post.

A fundraiser for Grimm, Diana Durand, was arrested this month on charges she illegally funneled more than $10,000 to his campaign.
