Members of the People’s Convoy, a group primarily comprising truckers protesting COVID-19 mandates, filed a lawsuit Monday claiming the Washington, D.C., government violated their First Amendment rights.

Sixteen members of the trucking convoy claimed that D.C.’s Metropolitan Police Department set up blockades preventing their access to the city.

"MPD formed the blockades for the sole purpose of preventing American citizens from entering our nation’s capital to exercise their constitutionally protected right to free speech,” the lawsuit states. “Of course, such action under color of state law violates Plaintiffs’ First Amendment rights.”

The lawsuit claims that the convoy was turned away from entering D.C. four separate times.

Throughout the month of March, the truckers took to the roads surrounding the nation’s capital to protest COVID-19 mandates and the national state of emergency. On March 27, the convoy announced it would leave D.C. and head to California to focus on specific pandemic-related measures there.

"I think stopping those is more important at this point in time than getting the emergency declaration repealed because that's already in place, and we need to stop stuff like these bills from getting in place," convoy organizer Mike Landis said. "Otherwise, the rest of us that don’t live in California are going to end up subject to the same situation."
