From USA TODAY.

While President Donald Trump delivers his State of the Union address on Feb. 24, a roster of influential actors, elected officials, cultural figures, journalists and veterans will assemble just a few minutes away in Washington to deliver a live rebuttal.

The "State of the Swamp" counter-address, headlined by actor Robert De Niro, is set to take place at the same time the president speaks to a joint session of Congress about the nation’s affairs and his policy agenda. Invoking the frog as a symbol of opposition to Trump, the event’s title references the swampy terrain of the nation’s capital.

Here’s what to expect from "State of the Swamp," including who will be in attendance and the meaning behind the event.

The "State of the Swamp" is organized by anti-Trump group Defiance.org, the "artist-activist" coalition Portland Frog Brigade and advocacy media network Courier. The event is a live counter-address "focused on defying Donald Trump’s abuses of power, including officials who previously advised Trump," according to a Feb. 17 statement from organizers.

"This is not a protest or a watch party," Defiance.org co-founder Miles Taylor said in the statement. "It’s a live, public rebuttal."

The event will include live music, satire, speeches and direct calls to action, according to organizers.
