Rosie O’Donnell plans to lead a protest against President Trump outside the White House just hours before he delivers his first address to Congress.

The Broadway vet and former daytime talk show host will be among the “thousands” expected at Tuesday’s “Resistance Address,” according to guidance sent out by organizers. The effort is aimed at “sending a clear message outside of Trump’s front door that his agenda does not represent the values of the American people,” a news release says.

“The rally will feature speakers from diverse organizations and groups of people who have been impacted and harmed by the Trump administration’s policies, including women, people of color and members of the LGBTQ community, as well as environmental and immigrants' rights groups,” according to a statement.

Organizations participating in the rally in Washington’s Lafayette Park include the American Civil Liberties Union, MoveOn.org, Food & Water Watch, National Nurses United and Our Revolution, among others.

O’Donnell and Trump have been engaged in a longtime, ongoing war of words. Trump, 70, once called the 54-year-old comedian a “pig,” saying during a presidential debate last year that O’Donnell “deserved” his verbal attacks. O’Donnell has dubbed Trump “mentally unstable” and has accused him of “treason.”

White House press secretary Sean Spicer said that the theme of Trump’s Tuesday address to Congress — which isn’t technically a State of the Union — will be “renewal of the American spirit.”
