Mark Warner pushing business bona fides in reelection campaign

      RICHMOND, Va. (AP) - Democratic Sen. Mark Warner is highlighting his background as a businessman during a statewide re-election campaign tour.

      Warner was in Richmond Thursday at 804RVA, a shared workspace for start-ups and freelancers.

      The first-term senator and former governor stressed the need for student loan reform so that more young people could pursue careers as entrepreneurs.

      Warner, a multi-millionaire cellphone pioneer, said he was not burdened by heavy student debt when some of his early start-ups failed.

      Republicans will pick Warner's challenger next month at a convention in Roanoke.

      Former Republican National Committee Chairman Ed Gillespie is considered the favorite to win the GOP nomination. He has called Warner a rubber stamp for President Barack Obama.

      Warner said Thursday he's not concerned about attacks questioning his political independence.
