Doctor-Turned-Sen. Roger Marshall Predicts Joe Biden Only Has 6 Months Until Total Incapacitation

Republican Kansas Sen. Roger Marshall predicted that former President Joe Biden has six months left until total incapacitation Thursday on the “Vince” podcast with host Vince Coglianese.

The former obstetrician and gynecologist discussed the implications of the diagnosis, what it means for the legitimacy of Biden’s presidency as Coglianese asked him whether anything can be done to address the situation.

“We would be in a full-blown constitutional crisis if the president of the United States were an invalid, incapable of doing the job, and other people were doing it for him. That’s completely unconstitutional, senator. Shouldn’t there be a way to address this?” he asked.

“So there absolutely is. And there needs to be some type of hearings and investigations on it,” Marshall responded.

“One last point I want to make here, Vince, is that the next chapter in this book is that Joe Biden is going to be totally mentally incapacitated in six months.” (RELATED: Biden Uses Final Hours Of Presidency To Let Fauci, Others Off The Hook)

“And they are going to say, ‘oh, this is metastatic prostate cancer as cognitive decline, and really it’s the last chapter of Alzheimer’s.’ So we’ll come back in six months and see where we are,” the senator continued.

For four years, the Biden Administration lied to the American people. Even after leaving office, the deception continues.

Marshall’s remarks to Coglianese contribute to growing scrutiny from both the media and the public over how Biden’s reportedly “aggressive” prostate cancer might have gone undetected.

Coglianese went on to highlight that even while Biden was present at Trump’s inauguration, the pardons issued at that time were executed using an auto pen. He named Anthony Fauci as an example of individuals who received preemptive pardons for alleged crimes they had not been convicted of.

“If you are saying he didn’t even have a role in that, it does seem worthy of an intense examination about to what extent all of that was completely invalid,” Coglianese asked.

“That needs to be litigated somehow, some way,” Marshall said. “Let alone the president [being] mentally competent when he made those.”
