Michael Avenatti, the attorney for adult-film star Stormy Daniels, on Wednesday called for the Supreme Court to add two seats to the bench, saying that the 2020 Democratic presidential candidate must commit to this position during the campaign.

"In light of the [Merrick] Garland seat that was stolen, together with the events of today and the hiding of docs, etc., the court must be expanded to 11 seats after 2020," Avenatti tweeted, referring to former President Obama's Supreme Court nominee.

Senate Republicans declined to consider Garland's nomination in 2016.

"The Dem nominee must commit to this or not receive the nomination IMO," Avenatti added. "There is far too much at stake."

Avenatti's comments came just hours after the first day of hearings for President Trump's Supreme Court nominee, Brett Kavanaugh, wrapped up.

The day was marked by feuds between Republican and Democratic lawmakers. Many Democrats called for the proceedings to be delayed due to the lack of records they've received on Kavanaugh's legal career.

Democrats also voiced outrage at the fact that 42,000 pages of documents related to Kavanaugh's work inside the George W. Bush administration were released the day before the hearing began.

Senate Judiciary Committee Chairman Charles Grassley (R-Iowa) rejected requests for an adjournment, however, and the hearings are expected to carry on this week. Many believe Kavanaugh's appointment to the Supreme Court could sway the bench to conservatives for decades.

Avenatti's call comes as he publicly voices the possibility that he would run for president in 2020. He said to The Hill earlier this year that the Democratic Party needs "a street fighter ... someone that can give as good as they take."

Avenatti is representing Daniels in her lawsuit against Trump and his former lawyer, Michael Cohen, over a nondisclosure agreement that was used to keep her quiet about an alleged affair between the adult-film star and the president.
