Turns out that House Speaker Paul D. Ryan isn’t just a policy wonk. He’s also a fundraising powerhouse as he works to preserve the Republican majority this fall.

Ryan hauled in nearly $15.6 million for the second quarter ending June 30, his team said, for a total of $37.9 million since he became speaker last fall.

That’s providing record levels of “cash on hand” for House Republicans, who hold a robust majority, but could face political headwinds with Donald Trump as the party’s nominee.

“Paul Ryan is committed to doing whatever it takes to make sure Republicans are re-elected on Election Day,” said Kevin Seifert, executive director of Team Ryan, the speaker’s political operation. “These funds will provide the tactical support for incumbents and challengers to be successful.”

Fundraising reports are due Friday. Ryan has transferred $25 million to the National Republican Congressional Committee, the House GOP’s campaign arm, including $5.4 million in June.

Rep. Greg Walden (R-Ore.), the NRCC chairman, said Ryan is sought after among donors who are “hungry” for his ability to jump into the policy weeds and present his legislative ideas for the GOP majority.

Ryan emerged as a reluctant speaker, who rose to leadership on the condition he would still be able to spend weekends at home in Wisconsin with his family and young children.

But he has managed to visit 18 states since taking the speaker’s gavel, hitting more than 71 events across the country in 43 cities, his team said.

As Congress recesses for the long summer break, Ryan has an “aggressive stretch” ahead, according to his team, popping into 12 states in August in another push for donations ahead of the November election.
