More from CNN Senior Congressional Correspondent Dana Bash’s interview with House Speaker John Boehner at the convention in Tampa:

Boehner (talking about Romney): "He is a very shy guy. He is a humble guy. He doesn't like to talk about himself. It’s, that's who he is. But I've known Mitt Romney for a long time. Decent, honest, hard-working guy. And I think Thursday he’ll have a chance to reintroduce himself to the American people. He never really had that chance. He's been locked in this Republican primary and then locked into this battle with the president. And as a result, people have all different kind of views of him. So I think Thursday night is clearly an important speech for him and I think he'll have a chance to reintroduce himself to the American people, most of whom are just paying attention now."
