He suggested Clinton choose Warren as her running mate because "without that [woman] card she would get nobody voting for her."
Trump toned down his attacks on members of his own party considerably, but still doled them out to his most recent critics, calling Jeb Bush "low-key — "I wanted to say 'low-key' cause its nicer than saying 'low-energy,'" he joked — and telling the crowd Sen. Lindsey Graham "knows less about the military than my 10 year old son Barron."
Both Graham and Bush have refused to support Trump in the days since he became the last man standing in the GOP primary, even as other Republicans have fallen in line.
Trump also dismissed House Speaker Paul Ryan's refusal to back him as Paul simply "trying to be cute," noting they previously had a very pleasant phone conversation three weeks ago.
But mostly, Trump seemed tickled, if also somewhat chagrined, by the fact that many of the remaining holdouts signed a pledge from the Republican National Committee promising to back the eventual nominee — a ploy initially used by the RNC to ensure Trump wouldn't launch a third-party bid.
"I signed a pledge, and they're the ones that are violating it!" he said. He dismissed, however, the holdouts, telling the crowd he "released" them.
"If somebody doesn't wanna endorse, I don't want their endorsement," he said.
Trump delivered the speech, his second of the day, in deep-blue Oregon to a backdrop of protests bubbling outside and a few scattered protests inside. Despite their best efforts to goad Trump supporters into a confrontation — protesters shouted "Racist!" and "Heil Trump!" at supporters as they walked through the gates — the protests went off peacefully, with police keeping them far away, and blocked off by a fence, from the arena.
But despite the blue tint of the state, Trump promised to win it in the general.
"We are going to carry your state in November," he said, to cheers from the crowd.
