Former President Barack Obama seemingly attempted to silence his own former White House physician for daring to expose Joe Biden’s slipping mental health ahead of the election.

According to his new memoir, “Holding the Line: A Lifetime of Defending Democracy and American Values,” Rep. Ronny Jackson (R-TX) writes about an email sent to him by former President Barack Obama about then-presidential candidate Biden’s “crazy statements and concerning mental gaffes.”

In 2020, when Jackson himself was running for Congress, the leftist media’s blatant willingness to ignore Biden’s fragile cognitive state was a key issue for him.

At the time, he retweeted a video of Biden’s “latest cognitive misadventure” with the message: “Remember the cognitive test that I gave @realDonaldTrump? The one he aced! Sounds like somebody else might need some testing done!! Scary!!”

Within 20 minutes of that tweet, Jackson received a “scathing” email from his former boss, President Obama, pressuring him to stop criticizing Biden going forward.

“I have made a point of not commenting on your service in my successor’s administration and have always spoken highly of you both in public and in private. You always served me and my family well, and I have considered you not only a fine doctor and service member but also a friend,” Obama wrote in the email.

“That’s why I have to express my disappointment at the cheap shot you took at Joe Biden via Twitter. It was unprofessional and beneath the office that you once held. It was also disrespectful to me and the many friends you had in our administration. You were the personal physician to the President of the United States as well as an admiral in the U.S. Navy. I expect better, and I hope upon reflection that you will expect more of yourself in the future,” Obama continued.

Infuriated by the email, Rep. Jackson considered whether to call the former president, before ultimately deciding not to respond.

“So, upon reflection, I thought, You know what? Screw that guy! I’m not doing it,” Jackson wrote. “I just walked away from it, which was the last time I had any contact with [Obama],” he added.

“It’s awfully ironic now, considering [Biden’s mental fitness] is all anyone, including the liberal media, can talk about,” Jackson said.

“Let it be known, as the White House physician for the last three presidents, I was the first to say that we have a serious problem with this man’s cognitive demise, and he will not make it four years in office. I’ve always said there would come a point where it wouldn’t be just me talking about it, but his own party, and sadly, that has proven to be the case. Joe Biden’s cognitive failures are on full display for the whole world to see,” Jackson said.
