(CNN) Protesters opposed to Brett Kavanaugh's appointment to the US Supreme Court swarmed over Washington on Saturday -- massing at the Capitol, disrupting the confirmation vote in the Senate and banging on the Supreme Court building doors when Kavanaugh arrived to be sworn in.

About 5:45 p.m. ET Saturday, a large crowd of protesters surged onto the front steps of the Supreme Court, chanting, "Hey hey, ho ho, Kavanaugh has got to go."

After police pushed them back from the doors, the demonstrators held signs and chanted, "No justice, no peace," and "We believe Anita Hill," a reference to the woman who accused Justice Clarence Thomas of misconduct.

It's not known if Kavanaugh heard the protesters. Police cleared the steps of the court about 6:15 p.m. and set up barriers.

Protesters showed theire disapproval on the Supreme Court steps after Kavanaugh was confirmed.

Earlier, Capitol Police said 14 people were arrested for protests in the Senate Gallery, 13 during the successful vote to confirm Kavanaugh and one a short time earlier.
