A group of Broadway performers made their voices heard at 1600 Pennsylvania Avenue when they staged a musical protest outside the White House.

According to The Hollywood Reporter, Rosie O’Donnell was joined by actors from some of Broadway’s top musicals on Monday to serenade President Donald Trump, as performers held signs that spelled out “Treason” and “Lock Him Up.”

Associated Press first reported details of the protest, with Rosie O’Donnell joined by current and former cast members of “Wicked”, ″Beautiful”, ″Hamilton”, ″Phantom of the Opera”, ″The King and I”, ″Les Miserables”, ″Cinderella”, ″Xanadu”, ″The Producers”, ″Head Over Heels”, culminating with a sing-along of “America the Beautiful”.

“Let the president know in no uncertain terms that we are alive, awake and we are woke,” O’Donnell told the crowd during the event, part of an ongoing anti-Trump protest that has been going on for more than three weeks.

“We hope to give you a nice little show and remind you that your voice is important,” said O’Donnell. “Whether it’s here in Washington, D.C., or in the town where you live, let your voice be heard.”

Organized by Seth Rudetsky and James Wesley of Sirius XM’s “On Broadway”, the protest with was livestreamed on social media.

O’Donnell has a long, nasty history with Trump, with the former stars of “The View” and “The Apprentice” respectively engaged in a years-long public feud.
