Proud Boys leader pleads guilty to burning DC church's Black Lives Matter banner

(CNN) The leader of the far-right Proud Boys pleaded guilty Monday to two misdemeanors stemming from his conduct in Washington, DC, amid violent pro-Donald Trump protests in December.

Enrique Tarrio appeared in DC Superior Court to plead guilty to property destruction for burning a Black Lives Matter banner that belonged to a historic Black church in DC. He also pleaded guilty to attempted possession of a high-capacity magazine, a violation of local gun control laws.

He will be sentenced next month and could face up to one year in jail, though defendants rarely get the maximum penalty. The charges were filed in local DC court and are separate from the sprawling federal investigation into the January 6 Capitol insurrection -- during which dozens of Proud Boys stormed the building and have since been charged with conspiracy and other crimes.

"Nothing in this plea agreement is intended to prevent the government from bringing different, additional charges against your client based on his conduct on January 6, 2021, or at any other time," prosecutors wrote in the four-page plea deal that Tarrio signed Monday.

Tarrio wasn't near the Capitol that day because he was arrested earlier that week on the local weapons and property destruction charges, and ordered to stay out of DC. Federal authorities later said his arrested was intentionally choreographed to keep him off the streets on January 6.
