Capitol Police arrested many of the protesters, including comedian and actress Amy Schumer.
While many New Yorkers, including Schumer, headed to D.C. for the sit-in, hundreds of people stayed in the city to protest outside of Trump Tower in Midtown on Thursday evening.
The loud and passionate crowd on 5th Avenue said they were were determined to stop Kavanaugh's confirmation.
The latest protests come as Senators pore over the FBI's investigation into the sexual misconduct allegations against Kavanaugh.
Some Senators said the report was very thorough, but top Democrats criticized the report as "incomplete" and "very limited."
Some raised the issue of Kavanaugh's temperament during the hearings.
He responded with an Op-Ed for the Wall Street Journal on Thursday night addressing the issue, saying in part:
"I was very emotional last Thursday, more so than I have ever been. I might have been too emotional at times. I know that my tone was sharp, and I said a few things I should not have said. I hope everyone can understand that I was there as a son, husband and dad. I testified with five people foremost in my mind: My mom and dad, my wife and most of all, my two daughters."
The Senate plans to vote to end debate on Kavanaugh's nomination on Friday morning, and set up a full floor vote that is expected on Saturday.
