Appearing on MSNBC's AM Joy, Dr. Corey Hébert -- the Chief Executive Officer of Community Health TV -- slammed Donald Trump's personal physician for allowing the president to dictate a letter describing Trump as the "healthiest individual ever elected to the presidency" - then suggested the two were conspiring to hide something.

Speaking with host Joy Reid, Hébert said he was not surprised that the controversial letter -- previously attributed to gastroenterologist Harold Bornstein -- was inaccurate at best.

"I hate to be this guy and say, 'America, I told you so,' but guess what? I told you so," the doctor quipped. "I mean, let's just start from the top. We now know what Trump did and Bornstein did. It was unethical, it was morally reprehensible and it flies in the face of democracy. But let's be very clear: This is not about Democrats and Republicans, it is really about two thing, deceit and hubris -- and actually, possibly, mental instability."

"What they basically did was allow someone to write their own medical record," he elaborated. "Think about that, who does that? And then use superlative language like you're the healthiest president that's ever lived? We all knew that was Donald Trump. The fact that he put this, albeit, weird doctor, in that place constitutes fraud -- it really does."

Hébert later described the reason why Trump has his medical records taken by his bodyguard, Keith Schiller, focusing on the hair-restoring medication Propecia.

"Propecia is to grow hair and also for benign prostatic hyperplasia, which is something that happened to old guys," he explained. "So you want somebody to think that you are young. You don't want them thinking you're losing your hair or that you can't urinate because your prostate is swollen. So he doesn't want people to know because he want them to think he's 45 -- but he's not, in more ways than one."
