Laurence Tribe accused McConnell of hypocrisy in a concise yet blistering tweet that has gone viral.
McConnell infamously did not allow Merrick Garland, who was former President Barack Obama‘s Supreme Court nominee, a hearing in 2016 because he said it was too close to the presidential election.
“Hypocrisy is McTurtle’s middle name,” wrote Tribe. “And his first and last name too.”
“What a flagrant dickhead!” he added.
Tribe has become a vocal critic of Trump and earlier this year sought an injunction against the president’s national emergency to secure funds to build a wall on the U.S.-Mexico border.
Earlier on Thursday, Tribe also mocked Trump for claiming the word “impeachment” is “dirty,” “filthy” and “disgusting.”
