WASHINGTON -- A Virginia man has been charged in federal court in the shooting of a security guard at the headquarters of a conservative Christian lobbying group.

Federal authorities say Floyd Lee Corkins II told a guard at the Family Research Council, "I don't like your politics" before shooting him in the arm. The guard and others helped subdue Corkins, who was taken into custody.

He's been charged with assault with intent to kill and with bringing a firearm across state lines.

Authorities found a box of ammunition and 15 Chick-fil-A sandwiches in his backpack.
