By holding out, Ryan is buying time for House Republicans to roll out their election-year agenda in hopes it will help shape the GOP presidential nominee’s own general-election platform.

He’s also signaling he will not bow to pressure from the candidate, his surrogates or the media.

GOP colleagues say the Speaker wants concessions from Trump. He wants the presumptive GOP nominee to tone down the rhetoric, moderate some controversial positions and commit himself to core conservative values.

“The Speaker is going to be under a lot of pressure to support the nominee, notwithstanding his reservations about some of Trump’s policy positions,” said one senior House Republican who is close to Ryan. “But Paul is committed to his agenda. He wants to make sure Donald Trump gives it fair consideration and that Donald Trump embraces some of this stuff.”
