Comedian Rosie O'Donnell led a group of Broadway performers in a musical protest of the Trump administration Monday night in front of the White House.

"Let the president know in no uncertain terms that we are alive, awake and we are woke," O'Donnell said to the crowd, part of an ongoing anti-Trump protest now on its 22nd consecutive night.

After warming up their voices with "America the Beautiful," the performers sang several show-tune favorites, such as "Do You Hear the People Sing?" from "Les Miserables," "Let The Sun Shine In" from "Hair" and "Climb Ev'ry Mountain" from "The Sound of Music."

They were led by Seth Rudetsky, a host on the SiriusXM channel "On Broadway," who helped O'Donnell organize the event.

"We hope to give you a nice little show and remind you that your voice is important," O'Donnell, a frequent and longtime critic of President Trump, said. "Whether it's here in Washington, D.C., or in the town where you live, let your voice be heard."

Some of those in Lafayette Square as part of the "Kremlin Annex" protest were into their third week at the event, even as Trump vacations at his New Jersey golf club.

Protesters gathered Monday with an array of anti-Trump signs, many focused on alleged conspiracy between the Trump campaign and the Russian government.

Two of the most popular chants of the night were "Lock him up!" and "Putin's puppet!"

Kristin Mink, the woman who confronted Scott Pruitt and told him to resign three days before he stepped down as head of the Environmental Protection Agency, spoke to the crowd.

"Every person who cares about switching over this administration, about having a Congress that's going to hold them accountable, every person needs to be getting more than themselves to the polls," Mink said. She had the word "vote" shaved into the side of her head.

Jim Obergefell, the named plaintiff in the Obergefell v. Hodges Supreme Court ruling that legalized same-sex marriage across the United States, warned against Trump's latest nominee to the Supreme Court.

"Brett Kavanaugh should not sit on our highest court. He is a danger to every marginalized community," Obergefell said. "Our president - well, not my president, someone else's president - is a threat to every marginalized community."
