A federal grand jury on Wednesday indicted a Virginia man on new terrorism charges for allegedly shooting a security guard at the Family Research Council (FRC) in Washington, D.C., this summer.

The Justice Department is charging Floyd Lee Corkins, 28, with committing an act of terrorism while armed, attempted murder while armed, aggravated assault while armed and second-degree burglary while armed.

The new charges are in addition to an indictment for possessing and transporting a firearm into D.C. for the purpose of committing a violent crime. The government filed those charges against Corkins in August, immediately following the shooting, which wounded a security guard at the conservative Christian group’s headquarters.
