The American people know the economy is too weak. Too many of them are suffering. So the question for Washington is, are we going to continue to play political games and - and - or are we going to say, we can do something right now to create jobs, to put money in the pockets of the middle-class, hire construction workers, teachers, veterans?

Sometimes politics is viewed as a boxing match. So, let's look at movies of last year. You know, you prepare for match like creed. Trump is like "Mad Max: Fury Road." We have never seen anything like this in politics. The kind of race he's going to run. I mean, look, he is winning the nomination. He doesn't prepare for debates. He doesn't run advertising. He gets millions of dollars spent against him, it has no effect, he's not running as sophisticated data driven campaign yet he is winning. As each and every day, you just don't know what you're going to get with this guy.

I think what should be celebrated about our campaign is we have over 3 million people who have contributed to our campaign - teachers, firefighters, nurses, retirees. They're making up the backbone of this field organization in the country.

But absent tax reform, the president believes the right way to get our fiscal house in order is ask the wealthy to pay their fair share.
