Donald Trump suggested Wednesday that House Speaker Paul Ryan (R-WI) was part of some “sinister” deal to to undermine his candidacy, citing Ryan’s failure to congratulate him on his Sunday night debate performance.

“Wouldn’t you think that Paul Ryan would say ‘Good going’? In front of just about the largest audience for a second night debate in the history of the country?” Trump began. “You’d think they would say ‘Great going, Don. Let’s go. Let’s beat this crook. She’s a crook. Let’s beat her. We’ve got to stop it!’”

“No, he doesn’t do that,” Trump said as the crowd booed along. “There is a whole deal going on there. There is a whole deal going on and we’re going to figure it out. I always figure things out. But there’s a whole sinister deal going on.”

On a conference call with fellow Republicans Monday, Ryan said he would not hold any campaign events with Trump before Election Day and would instead focus his energy on defending the Republican majority in Congress.

Before he attacked Ryan Wednesday, Trump had pointed to a supportive article by Pat Buchanan, which Trump said claimed that he delivered “the single greatest debate performance in the history of presidential politics” on Sunday night. In fact, Buchanan, who Trump in 2000 wrote defended Hitler, described Trump’s performance “the most effective” in the history of presidential debates.
