Former White House physician-turned-GOP Rep. Ronnie Jackson dished on details of a “scathing” email he says he received from former President Barack Obama after Jackson called on President Joe Biden to undergo a mental fitness exam.

“He just tore me up,” Jackson told House colleague Rep. Jim Banks, R‑Ind., during a podcast this week, noting that Obama accused him of being disloyal.

“An entire page about how disappointed he was in me and how it’s beneath me as a physician and beneath me as an officer in the military to be attacking Joe Biden like this. And it was a betrayal of the trust that he and his administration put in me and he was so disappointed in me and yada, yada,” Jackson, a former Navy doctor who worked in the George W. Bush and Donald Trump administrations, as well as for Obama.
