KNOXVILLE, Tenn. (AP) -- A federal judge has refused to dismiss an indictment against a Georgia man charged with traveling armed to East Tennessee to possibly take over the Monroe County Courthouse after a grand jury refused to indict President Barack Obama.

The judge in Knoxville denied a defense motion contending that charges of transporting a firearm in furtherance of a civil disorder and using a firearm in relation to a violent felony crime charge Darren Wesley Huff of Dallas, Ga., twice for the same conduct.

Huff's attorney did not return a message seeking comment Monday.

Huff is accused of threatening to take over the courthouse at Madisonville after a grand jury foreman refused to indict the president on charges related to proof of his birthplace.

The case is set for trial Aug. 16.
