Republican US House Speaker Ryan backs Trump after long courtship

'HEAL THE FISSURES'

Ryan met Trump in a high-profile meeting last month and they have since had a number of telephone calls.

"It's no secret that he and I have our differences. I won't pretend otherwise," Ryan wrote. "And when I feel the need to, I'll continue to speak my mind. But the reality is, on the issues that make up our agenda, we have more common ground than disagreement."

Ryan said he and Trump had spoken many times in recent weeks about how, "by focusing on issues that unite Republicans, we can work together to heal the fissures developed through the primary."

"Through these conversations, I feel confident he would help us turn the ideas in this agenda into laws to help improve people's lives. That's why I'll be voting for him this fall," Ryan said.

Announcing he will vote for Trump should make it a bit more comfortable for Ryan to chair the party's nominating convention in Cleveland.

While Ryan's endorsement was significant for Trump, there remain many concerns about him within the party.

Longtime Republican financier Fred Malek drew attention to worries about Trump in a column in the Washington Post on Thursday. He cited Trump's criticism last week of New Mexico's Republican governor, Susana Martinez, considered a rising star in the party with the ability to appeal to Hispanics.

"These attacks on fellow Republicans must stop as we move closer to the general election," Malek wrote.

Senate Majority Leader Mitch McConnell, a Kentucky Republican, who has said he will support Trump, told CNN that Trump's proposed Muslim ban was a bad idea and that his criticism of Martinez was ill-advised.

Ryan said he too still had concerns about Trump's tone.

"It is my hope the campaign improves its tone as we go forward and it's all a campaign we can be proud of," Ryan told the Associated Press.
