The host of MSNBC’s “Morning Joe” revealed that sources close to President Trump believe he is mentally unfit to remain in office.

Joe Scarborough, a former GOP lawmaker, said that during the campaign, people close to Trump told him that Trump had “early stages of dementia.”

Citing a New York Daily News editorial that said Trump was “profoundly unstable,” Scarborough declared that Trump was “completely detached from reality.”

Scarborough also said the U.S. is edging closer to war with North Korea than most Americans know, and that the White House has long believed this was going to be the case.

Scarborough has become a frequent critic of Trump, who in turn has engaged in a war of words with the MSNBC host on Twitter, where he has attacked Scarborough and his co-host and fiance Mika Brzezinski. Trump escalated the feud with a plunge into a conspiracy theory that Scarborough killed a staffer who was found dead in his Congressional district office in Florida in 2001.

Trump on Twitter yesterday referred to the conspiracy theory that there is a “deep state” working against him that included the FBI, and during an interview with CNN, Trump’s “The Art of the Deal” ghostwriter said the president is “losing his grip on reality.”

While much of Scarborough’s declaration seems like conjecture, there is clearly a growing body of evidence to support the notion many have brought up that something could be wrong within the White House.

Scarborough again referenced the 25th Amendment to the Constitution, which lays out the process to replace the president or the vice president in the event of their death, disabilities, resignation, or general incapacitation.
