High-profile attorney Michael Avenatti on Friday said he supports a "full and complete FBI investigation" into allegations against the nominee.

Avenatti went one step further, saying that impeachment of Kavanaugh should be a litmus test for any candidates hoping to the secure the Democractic nomination in 2020.

“I think the expansion to 11 [Supreme Court justices] should be a litmus test and I think the other litmus test should be a full and complete FBI investigation," Avenatti told the outlet. "[A]nd if it is shown that Brett Kavanaugh perjured himself or committed any of these acts, he absolutely should be removed from the Supreme Court."

Avenatti, who has said he will run for the presidency on the 2020 Democratic ticket, has lashed out at Republican members of the Senate Judiciary Committee in the lead up to and following its hearing for Kavanaugh and one of his accusers, Christine Blasey Ford.

Ford delivered a gripping testimony before the committee on Thursday, detailing her allegations of assault against Kavanaugh for the first time publicly. Kavanaugh, who testified after Ford, vehemently denied her allegations.

The lawyer issued a stern warning on Friday to Republicans on the committee, tweeting, “Warning - If the committee advances the nomination this afternoon, my client and I are going to thoroughly enjoy embarrassing @ChuckGrassley @LindseyGrahamSC @tedcruz and all of the other GOP members on the committee this weekend when her story is told and is deemed credible,” Friday afternoon.

“And if you think I am bluffing, you have not been paying attention the last 7 months. I don’t traffic in nonsense. I traffic in facts and evidence,” he added.

The comments came shortly before the Judiciary Committee advanced Kavanaugh’s nomination to the full Senate for a confirmation vote. The 11-10 panel vote was along party lines.

"I think it would be proper to delay the floor vote for up to but not more than one week in order to let the FBI do an investigation, limited in time and scope to the current allegations that are there," he said.

Avenatti released Swetnick’s allegations on Wednesday, tweeting out her sworn declaration outlining her allegations against Kavanaugh, including that he was present for a “gang rape” of which she was a victim.

Kavanaugh has denied all allegations of sexual misconduct against him, doing so again in his testimony before the Senate panel on Thursday.
