President Trump went on a nearly 10-minute rant, falsely accusing the media of reporting that he had a "massive heart attack" and that he stayed over night at Walter Reed National Military Medical Center — neither of which were reported by any credible, mainstream news outlets.

Trump specifically targeted CNN over the coverage of his visit at the start of his rant as "stupid, corrupt, horrible CNN." CNN at no point reported that Trump had a heart attack or chest pains, which Trump claimed the media had reported.

"They said I had a massive heart attack and it wasn’t true, they knew it wasn’t true, they were with me," Trump said of the media.

In a story riddled with "sir" mentions, Trump claimed that as he returned to the White House, multiple people began asking him, "Sir, are you OK?"

"I said, 'Yeah what’s that all about?'" Trump said. "I go a few feet further and another security said, 'Sir, are you ok, sir?' and I said, 'Yeah I’m fine.' Nobody’s ever asked me that."

Trump then claimed that after pushback, the media instead began reporting that he had "tremendous chest pains," which was also not reported by any mainstream news outlets.

He also offered a new version of how he came to go to Walter Reed on a Saturday for what he claimed was a "routine" visit.

While the White House physician explained in a memo that the visit was kept off the record due to "scheduling uncertainties" — not because it was spur of the moment — Trump claimed that the White House physician called him on Saturday and said: "Sir, you're home today...I wondered, maybe, could I do some of the physical?"
