Straining to mend their party after months of chaos, Donald Trump and House Speaker Paul Ryan declared themselves "totally committed" to working together after a fence-mending personal meeting on Thursday. Ryan suggested that after initial hesitance, he may well end up endorsing the GOP candidate for president.

"We will have policy disputes. There is no two ways about that. The question is, can we unify on the common core principles that make our party?" Ryan said. "And I'm very encouraged that the answer to that question is yes."

Trump broadcast his own enthusiasm. "I really think we had a great meeting today, and I think we agree on a lot of things and it'll be a little process but it'll come along. I'm pretty sure," he said.
