Two people climbed flagpoles outside Union Station Saturday afternoon and unveiled a banner that read "Don't Trump our communities" in a peaceful demonstration that led to six arrests.

Coinciding with a day of women's marches around the world, the protest occurred in the plaza at Columbus Circle outside the D.C. transportation hub. Activists handed out cupcakes with notes and fliers arguing that prosecutors should drop all charges against people arrested in protests on the day of President Trump's inauguration. On Thursday, the U.S. attorney's office in the District announced it was dismissing charges against 129 people awaiting trial but that prosecutors plan to move forward with 59 cases.

"We're going to keep fighting until all the charges are dismissed and we're going to keep fighting until we have the kind of world where every human being, regardless of the color of their skin, their gender, their gender identification, their sexual orientation, their immigration status, has rights, equity and support and solidarity," said David Thurston, 39, who identifies as black and queer and lives in Washington.

The flagpole climbers and four others were arrested and charged with failure to obey a lawful order after they were given three warnings to disperse, said Sgt. James Dingeldein, a spokesman for the U.S. Park Police.

Union Station was evacuated for unrelated reasons Saturday after a fire alarm went off, but there was no indication of an emergency when the department responded at 2:29 p.m, said Vito Maggiolo, a spokeman for D.C. Fire and Emergency Medical Services Department.
