GQ special correspondent Keith Olbermann has called onto resign after less than one week in office.

“It's time for Donald Trump to resign as president," Olbermann said on "The Resistance," an online GQ video series. "Admittedly, it's been an interesting couple of days. But for any patriotic American capable of adding two and two and not getting one-and-a-half million, this is enough."

"This man is not of sound mind," Olbermann added, cautioning that Trump remaining in office could mean "the end of civilization."

Olbermann's call for Trump's resignation comes after Trump's spokesman reiterated Trump's belief in a baseless claim that as many as 3 million illegal votes were cast in the 2016 election.

Olbermann also had repeatedly called for President George W. Bush and Vice President Dick Cheney to resign while hosting his MSNBC program, "Countdown."

MSNBC and Olbermann parted ways after it was revealed that the host had donated to the congressional campaigns of two Democrats running for office in 2011. He since has worked for the now-defunct Current TV and ESPN 2.

Olbermann's plea for Trump to resign has been viewed more than 230,000 times on GQ's YouTube channel, and the video has been viewed more than 3 million times on Facebook.

His MSNBC "Countdown" audience averaged about 1 million viewers per night in the show's final full year.
