Rep. Ronny Jackson (R-TX) is now dishing on an angry letter that he received from former President Barack Obama after Jackson began raising questions about Joe Biden’s cognitive health during the 2020 campaign.

Jackson was also the White House physician to Obama, as well as George W. Bush and Donald Trump.

Jackson noted how he saw the issues during the campaign with Biden and tweeted about them.

“Biden was on TV again, making crazy statements and concerning mental gaffes; he didn’t know what state he was in or what office he was campaigning for,” Jackson recalls of the 2020 campaign season. “He apparently thought at one point that he was running for the Senate and later couldn’t remember what state he was campaigning in. This had been going on for months and was getting worse.” [….]

“Trump never made crazy statements like the ones Biden was making almost every day,” Jackson writes in his book, “but these people were jumping up and down: ‘He’s not fit to be president; he needs a cognitive test!’”

In 2020, when Jackson himself was running for Congress, the media’s lack of attention to Biden’s cognitive frailty bothered him greatly. 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!!”

Jackson immediately got an angry email within minutes from Barack Obama.

“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 told Jackson.

Obama knew that they were selling Biden as the return to “norms,” the nice older “moderate” but that this — from a former White House physician — would be taken seriously and could hurt the Democrats’ effort to grab power. So it needed to be shut down immediately and blasted. But credit to Jackson that he didn’t stay quiet, that he put the interests of the country first (unlike Obama), but continued to question what was apparent to some of us, even at this point.

As Jackson noted, it cost him his friendship with Obama as he chose not to respond to the angry missive.

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

“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.

Now the NY Times is even acknowledging there are issues and that the White House is scrambling to try to deal with them — everything from trying to wall off the press when they don’t want questions to watching out for Biden when he walks because of his shuffling gate. Now we see things like him losing it on a reporter and denying all reality at the White House picnic. But it’s too late now and it hurt the whole country that Obama, the Democrats, and the media were so concentrated on Democratic power that they weren’t honest before or focused on what was best for America.
