GOP pushback builds against Trump primary picks: The Note

Former President Donald Trump’s hope of triumphs against incumbent governors appear to be fading in states including Georgia and Idaho.

The TAKE with Rick Klein

Former President Donald Trump won the first round in the primary season endorsement battle last week, with J.D. Vance's triumph in the GOP Senate primary in Ohio.

It only gets harder from here.

That fact landed directly in Trump's face Friday night when mentions of Dr. Mehmet Oz's name drew boos at the former president's Pennsylvania rally. Some attendees even turned their backs when Oz himself -- Trump's endorsed pick in the next big Senate race -- spoke to the crowd, as ABC News' Lalee Ibssa reported.
