RICHMOND, Va. (AP) - Hazardous materials teams and investigators combed the headquarters of a Republican congressional candidate in Chatham after a letter containing white powder was opened.
Robert Hurt's congressional campaign spokesman Sean Harrison says the powder was found in an envelope Hurt opened Friday afternoon.
Harrison says tests were being run on the substance. He says Hurt was with his family Friday evening.
Law-enforcement authorities declined to comment on the case.
Hurt is trying to move from Virginia's state Senate to the U.S. House of Representatives.
He is challenging first-term Democrat Tom Perriello for Virginia's 5th Congressional District seat.
The race is one of the nation's most closely watched midterm House races.
