U.S. Capitol Police arrested about 60 demonstrators Friday evening during a protest of the appearance of troops in Saturday’s Army celebration in Washington and at immigration protests in Los Angeles. More than 50 of those arrested were veterans, according to organizers.

Capitol Police said the arrests came after a bicycle-rack barrier was pushed down and a police line was “illegally crossed” as demonstrators ran toward the steps leading to the Capitol Rotunda.

The demonstrators, most wearing fatigue jackets with their names embroidered on them, then sat on the steps of the Capitol, behind a sign that read “Vets Say Military Off Our Streets.”

The 60 were part of a larger group that had been demonstrating peacefully at the Supreme Court, Capitol Police said.

After they broke away and ran toward the Capitol steps, officers “began making arrests,” police said.

The protest was organized by two veterans advocacy groups, About Face: Veterans Against the War, and Veterans for Peace, which held a news conference outside the Supreme Court building earlier in the evening that featured remarks from Army, Air Force, Marine and National Guard veterans. In a series of chants and speeches, they condemned what they called the Trump administration’s increased militarism domestically, including its response to anti-ICE protests, allocation of public funds to the Army parade, and continued support of Israel.

“We’re supposed to have a government with checks and balances, and we have a president who’s clearly acting with a disregard for the rule of law and for the Constitution,” said Brittany Ramos DeBarros, the group’s organizing director and an Army veteran.

Veterans and supporters from across the country were in attendance, including former service members as young as 20 and as old as 80, DeBarros said.

“We think that it’s important that the nation see that veterans are going to stand up to that, that our loyalty is to the values that this country says that it’s about,” DeBarros said.

Jeff Morris, a disabled veteran who relies on the government for disability checks and health care, flew from Melbourne, Florida, to Washington to participate in the news conference and watch the sit-in.

“It makes me proud that these service members have given so much and [are] still willing to stand for what they think is right,” he said.

Capitol Police said that all who were arrested will be charged with unlawful demonstration and crossing a police line. Additional charges for some will include assault on a police officer and resisting arrest, police said. Those arrested were released Friday night and Saturday morning, according to DeBarros. About eight will be arraigned Saturday afternoon.

During the Army celebration Saturday, other members of About Face will attend the arraignments and host a community teach-in at Anacostia Park as part of D.C. Joy Day, a community and parade counterprogramming event celebrating the city’s people and culture.
