Multiple Capitol Police officers filed a civil lawsuit against former President Trump, Roger Stone, and leaders of multiple right-wing groups on Thursday. The seven police officers filed the lawsuit with Washington, D.C. federal court against Trump and others over their alleged role in the Capitol riot on Jan. 6th.

The Hill reports:

The civil rights suit alleges Trump, acting in concert with groups like the Proud Boys and Oath Keepers, engaged in acts of domestic terrorism designed to unlawfully keep him in power despite losing the 2020 election.

The plaintiffs, five of whom are Black, say the effort was fueled by the defendants’ promotion of white supremacist-laden conspiracy theories and lies about the election being swayed by widespread voter fraud, particularly in areas with significant Black populations.

“As this lawsuit makes clear, the Jan. 6 insurrection was not just an attack on individuals, but an attack on democracy itself,” said Damon Hewitt, president of the Lawyers’ Committee for Civil Rights Under Law, which is representing the officers. “It was a blatant attempt to stifle the votes and voices of millions of Americans, particularly Black voters.”

In addition to naming Trump and his campaign as defendants, the lawsuit also implicated more than a dozen members of extremist groups and political organizations. Among those were Stone, a longtime right-wing provocateur and recipient of presidential clemency under Trump, who allegedly raised funds for the Jan. 6 pro-Trump event and was a key promoter of Trump’s “Big Lie.”

The lawsuit claims Trump and other defendants violated the Ku Klux Klan Act, an 1871 federal statute that made it illegal to use force or threat to prevent federal officials from carrying out their duties.
