“It’s like Donald Trump’s staff is sabotaging Trump by convincing him to make the worst possible endorsements,” conservative radio host Erick Erickson tweeted.

“This endorsement could divide MAGA in the only way that matters: he could lose America First conservatives over it,” Breitbart News’ Joel Pollak wrote.

Elsewhere, Rep. Mo Brooks (R-AL), who is running for the Senate and who has split with Trump in recent over back-and-forth accusations of election interference, chalked up the Oz endorsement to weak-kneaded staffers the ex-president has enlisted.

“This is happening because Trump’s surrounded himself by staff who are on McConnell’s payroll & hostile to the MAGA agenda. Everybody telling Trump who to endorse in primaries works for The Swamp,” said Brooks, whose Trump endorsement was recently rescinded. “They played him. Again.”
