White House Terrified Over 'Mentally Incapacitated' Trump's Government Shutdown: Howard Dean

President Trump's mental state was questioned yet again Sunday by a former Democratic governor and physician.

While discussing the government shutdown and border wall on MSNBC former governor of Vermont, Howard Dean called Trump "mentally incapacitated," on MSNBC, Raw Story reported.

"As I said before, I actually think the president is mentally incapacitated and I have thought so for quite some time," Dean said. "He says things that he knows aren't true and that somehow he thinks people are going to believe, and they just don't."

The 70-year-old physician referenced back to his comments he made in September, following the death of Senator John McCain.

"I've long believed the president is mentally ill," Dean said in September to MSNBC host Alex Witt. "And I believe narcissism overcomes his ability to know, A, what's good for the country, and B, what's good for him."

According to Dean, Trump is unable to be rational and no bargain will be able to be made.

"Essentially you can't really make a bargain with somebody who is irrational, because they won't keep it, and Republicans have been quoted off the record as saying such a thing," Dean said Sunday. "Republicans and the Democrats in Congress have got to do the best they can in the absence of a chief executive who is really a chief executive."

"As you know very well, his own staff is terrified of what's happening here ... This guy is a completely irrational person," he added.

MSNBC's political analyst, Susan Del Percio added her own comments, saying "Republicans are to blame" for the government shutdown.
