WASHINGTON, Nov. 13 (UPI) -- Thousands of protesters have descended on Washington as Refuse Fascism and nearly 20 partner groups mark the first week of their "Flood D.C." campaign to demand President Donald Trump's removal from office.

The movement, which has pledged to "surround the White House" every Monday for the rest of November, aims to become one of the largest sustained protest efforts since Trump's re-election. The difference from other demonstrations is they are calling for the removal of Trump and his administration officials.

Rafael Kadaris, a national organizer for Refuse Fascism, said that the movement's "single, unifying demand we have is that Trump must go now," emphasizing that sustained turnout "day after day" could "change the equation."

Founded in 2016, Refuse Fascism is a volunteer led organization with chapters in major United States cities. Its "Flood D.C." campaign began Nov. 5 with a rally at the Washington Monument, marking one year since Trump's re-election amid growing concerns over the administration's policies.

Refuse Fascism has partnered with organizations such as the National Organization for Women, For Liberation and Resistance Everywhere and United Native Americans.
