Thousand to that big night for president Obama. More than 30 million of us tuned in to his state of the union. A high stakes speech at the low point of his presidency that he used to confront congress and demand a raise for America. Let's bring in ABC's Jon Karl for more. The white house knows that one speech won't make a big difference without a follow-up campaign. Reporter: That's right and the president was out there hitting that give America a raise theme hard today in campaign-style events in Pennsylvania and Maryland. The white house believes this is a win/win issue for the president even if he cannot get congress to go along with an increase to the minimum wage, democrats, they believe, will have a campaign issue for the fall and look at the ABC news/"washington post" poll from last month showing overwhelming support for minimum wage increase, 66% favoring, just 31% opposing. So the president is going to push hard on that. There were great notes in the speech. That tribute to the army ranger Cory Remsburg and a shout-out from the president for house speaker John Boehner. Let's listen. Here in America our success should depend not on accident of birth, but the strength of our work ethic and the scope of our dreams. That's how the son of a barkeep is speaker of the house. A lot of cheers there, John, and there are some signs of a fall between the parties in the capitol. Reporter: There are some signs. The house overwhelmingly passed a trillion dollar farm bill that had been blocked for more than two years and republican leaders in the house are actually suggesting that they may be willing to move forward on immigration reform, that would be a big one for the white house. I wouldn't bet the ranch yet, but there is some progress there. The president's top legislative goal for the year. Jon Karl, thanks very much. Another story making headlines right after the president's speech a member of congress lost his cool threatened to kill a journalist. Unlucky for him it was all caught on camera. Today the congressman is apologizing and ABC's Jeff Zeleny looks at whether that's too little too late. I really have to go -- Reporter: Today New York congressman Michael Grimm was a model of contrition. I was wrong. It shouldn't have happened. Reporter: We saw a very different side of the congressman last night when he walked away after a reporter asked about an investigation against him. We wanted to get him on camera on that, but he, as you saw, refused to talk about that. Back to you. Reporter: Watch as the congressman returns. Let me be clear to you. You ever do that to me again, and I'll throw you off this -- Reporter: How's that? The congressman threatening to throw the reporter off the balcony and it gets worse. You're not man enough. You're not man enough. I'll break you in half like a boy. Reporter: Yes, that's right, a congressman saying "I'll break you in half like a boy." Congressman Grimm was elected during the tea party wave of 2010. A retired marine and former FBI agent, he's now under investigation by the FBI himself to determine whether he supplies Ted illegal campaign contributions, and that's what the reporter trying to ask him about when he stormed off. On capitol hill, the story played out all day long with one apology after another. I'm sure my Italian mother is going to be yelling at me saying, you weren't raised that way, and she's right. Reporter: It was not the state of the union response republicans had in mind. Jeff Zeleny, ABC news, the capitol.
