KNOXVILLE, Tenn. (AP) -- A Georgia militia supporter goes on trial Tuesday in Knoxville charged in a bizarre plan to take over a rural Tennessee courthouse and help serve citizens' arrest warrants on judges and law officers.

Federal court records show 41-year-old Darren Wesley Huff of Dallas, Ga., traveled in April 2010 to the Monroe County Courthouse between Chattanooga and Knoxville with a handgun and an AK-47 after telling FBI agents he planned to join in making citizens' arrests.

Huff is charged with carrying a firearm in interstate commerce with the intent to use it in a civil disorder. He is also charged with using a firearm in relation to another felony.

Huff and his attorney, G. Scott Green, have declined comment.

The federal jury trial is expected to last several days.
