The presidential nominee of the Republican party used a primetime television interview on a reliably Republican cable network to attack the record and character of the highest-ranking elected Republican in the country on Tuesday night.

“We have a group of people who want to see America be great again,” Donald Trump told Fox News host Bill O’Reilly. “And Paul Ryan – open borders, amnesty, and lots of other- bad budgets by the way, very very bad budgets.”

“I don’t want his support. I don’t care about his support,” he added later.

On Monday morning, Ryan told fellow house Republicans he would no longer defend Trump or his divisive comments; focusing instead on preserving congressional majorities in the house and senate.

That decision set off a mostly one-sided war with the Republican nominee, who attacked Ryan repeatedly on Twitter on Tuesday, and returned to his, and Senator John McCain’s, supposed disloyalty repeatedly in his interview with O’Reilly.

“The first sign of a little bit of difficulty [McCain] un-endorses. I wouldn’t want to be in a fox hole with a lot of these people, that I can tell you. Including Ryan,” Trump told O’Reilly. “Especially Ryan.”

Eighty seven sitting members of congress or governors have said they will not endorse or vote for Trump, a USA Today analysis found. Trump’s feud with these Republicans has overshadowed his broader message, including his attempts to use hacked Clinton campaign emails released by WikiLeaks against Clinton.

At a late rally in Panama City, Florida tonight, Trump mentioned WikiLeaks-released emails more than a dozen times.

He did not mention Ryan.
