Keith Olbermann absolutely unleashes on President Trump, calls him 'President Jackass'

Fair warning: you're going to want to put your headphones on for this one.

In the latest episode of his GQ web series “The Resistance,” Keith Olbermann did not hold back with a message of criticisms for his apparent least-favorite president, Donald Trump. He let so loose, in fact, that he called Trump a "jackass" 27 times in under six minutes. Impressive.

The commentator didn't only talk about Trump, though - he also went in on “triumph of double nepotism” Jared Kushner and Ivanka Trump.

Watch the Olbermann epically take down "President Jackass" below.

Note to self: don't get on Keith Olbermann's bad side.
