“The credit in reaching this goal goes to hundreds of grass-root volunteers who spent countless hours gathering petition signatures while I was busy on the people’s business in the Virginia General Assembly session,’’ Marshall said in a statement.

  The state GOP will verify the signatures. Candidates have until 5 p.m. Thursday to collect 10,000 signatures from across the state, including 400 from each of the state’s 11 congressional districts. If they submit more than 15,000, the party will count the signatures but not verify each one.

Former Virginia governor and U.S. senator George Allen and tea party activist Jamie Radtke submitted signatures earlier this month. Others in the GOP race include Hampton Roads lawyer David McCormick and Bishop Earl Jackson.
