Protests at the US Capitol on Monday led to some arrests as demonstrators gathered to oppose embattled Supreme Court nominee Brett Kavanaugh's confirmation to the high court.

The demonstrators sought to put pressure on Sen. Susan Collins, a potential swing vote, by showing up at her Dirksen Senate office. An aide from Collins' office came out into the hallway at one point to listen to the protestors.

The protestors implored the senator to take a stand sooner rather than later, saying: "Collins needs to make a decision now when it matters and stand up for us."

Another protestor indicated that she was still holding out hope that Collins would be a "no" vote on Kavanaugh's nomination, saying, "We believe that Senator Collins can be a hero."

Capitol Hill police worked to make sure that people had room to move throughout the hallways, and later arrests began to take place outside of Collins' office to protestors occupying the hallway.
