A petition calling for Supreme Court Justice Brett Kavanaugh to be impeached has gathered over 155,000 signatures in the wake of his confirmation and multiple allegations of sexual assault brought against him.

"Kavanaugh has been credibly accused of sexual assault and lying under oath in 2004, 2006 and at least 30 times during his Supreme Court confirmation hearings," the petition, organized by liberal group Credo Action, claims. "Perjury is an impeachable offense. The House Judiciary Committee should immediately investigate these accusations and work to remove Kavanaugh from the Supreme Court."

"Our activism forced Republicans' misogyny and hate into the spotlight and delayed the confirmation process for weeks," the petition continues. "Now it's time to unleash the same grassroots power on House members and demand that they use every tool at their disposal to impeach Kavanaugh."

So far, the petition has 158,686 signatures with a goal of 200,000.

Heidi Hess, co-director of Credo Action, told NBC News she believes "an accused sexual predator who committed perjury by repeatedly lying under oath to the Senate Judiciary Committee has no business being a judge - period."

"A majority of Americans opposed Kavanaugh's confirmation to the Supreme Court and we believe a majority will ultimately support his impeachment as well," Hess said, adding that the group will be particularly focusing on "making sure House Democrats know that progressives expect them to use their full power to get Kavanaugh off the bench if they gain control of the House."

President Trump over the weekend called on his supporters to back Republicans in the midterm elections and warned that Democrats have become "too extreme and too dangerous to govern."

"You don't hand matches to an arsonist, and you don't give power to an angry left-wing mob," Trump tweeted following a rally in Topeka, Kan.

"Democrats have become too EXTREME and TOO DANGEROUS to govern. Republicans believe in the rule of law - not the rule of the mob," he added.

Kavanaugh, who has denied all the accusations, will hear his first cases starting Tuesday.
