Keith Olbermann demands Trump be impeached after controversial CNN take down tweet

Liberals, Democrats and opponents of President Donald Trump are calling on him to resign or be impeached Sunday after he tweeted a video showing him literally taking down CNN.

Keith Olbermann, a liberal commentator and former television host for MSNBC, tweeted Sunday morning amid the controversy calling on others to support a call for impeachment against Trump.

"Please RT if you agree the cabinet must invoke the 25th Amendment, TODAY, and immediately remove @realDonaldTrump from the presidency," Olbermann wrote.

Olbermann is referring to the effort by a group of congressional Democrats rallying support for a bill that would create a congressional "oversight" panel with the intended goal of ruling Trump "incapacitated" or unable to carryout the duties of his office in order to remove him from office using the 25 Amendment in the Constitution.

The 25th Amendment was ratified in 1967 and established the presidential line-of-succession and what to do when a sitting president is "incapacitated." The purpose of the amendment was to address serious medical issues, but Democrats seem to believe the amendment can be used to remove Trump from office.

In all, 25 House Democrats have signed onto a piece of legislation by Rep. Jamie Raskin (D-Md.), a constitutional lawyer, that would use Congress to remove Trump using the 25th Amendment.

However, the bill is a long shot, given the requirements established by the Constitution and even Raskin's own bill. In the end, Vice President Mike Pence would have to give his approval in any case, according to the 25th Amendment, something that won't likely happen.

But Olbermann's tweet definitely struck a cord Sunday and it quickly garnered tens of thousands of retweets and "likes."

Olbermann's Sunday call for Trump to be impeached came less than 24 hours after his last one. On Saturday evening, in response to comments Trump made at an Independence Day event in Washington D.C., Olbermann said Trump should be impeached, indicted and imprisoned after he allegedly "attacked" freedom of speech.

Olbermann is currently host of "The Resistance," a political webcast for the GQ network.
