FBI Director to Herridge: 'We Do Investigations, Not Security Inquiries'

Eric Trump: Paul Ryan's Backing Is Not Necessary

Presumptive GOP nominee Donald Trump and House Speaker Paul Ryan (R-WI) released the following joint statement after their meeting in Washington, D.C.

The United States cannot afford another four years of the Obama White House, which is what Hillary Clinton represents. That is why it’s critical that Republicans unite around our shared principles, advance a conservative agenda, and do all we can to win this fall. With that focus, we had a great conversation this morning. While we were honest about our few differences, we recognize that there are also many important areas of common ground. We will be having additional discussions, but remain confident there’s a great opportunity to unify our party and win this fall, and we are totally committed to working together to achieve that goal. We are extremely proud of the fact that many millions of new voters have entered the primary system, far more than ever before in the Republican Party's history. This was our first meeting, but it was a very positive step toward unification.

Trump is also scheduled to meet with Senate Republican leaders today.

Ryan then took questions from the media on Capitol Hill, saying that the process of unifying the party is going to "take some time."

He said it's important that the GOP not have a "fake" unification process after the very divisive primaries.

"I'm very encouraged. I heard a lot of good things from our presumptive nominee and we exchanged differences of opinion on a number of things that everybody knows we have," said Ryan. 

He added, however, that many Republicans have disagreements on policy issues, but remain united on "core principles." 

Ryan said before today, he had only met Trump for about 30 seconds in 2012. Ryan recalled that he disagreed with some of Mitt Romney's policy positions while serving as the VP nominee four years ago.

Watch Ryan's comments above.
