Colorado Senate candidate Jane Norton (R) is calling on Sen. Michael Bennet (D-Colo.) to reveal what he knew about the White House’s job offer to primary rival Andrew Romanoff (D). 

"Andrew Romanoff answered the tough questions, and now it's time for the appointed senator to do the same," Norton said in a statement Thursday.

Romanoff released a statement Wednesday saying White House deputy chief of staff Jim Messina contacted him in September. Messina "suggested three positions that might be available to me were I not pursuing the Senate race," Romanoff said. "At no time was I promised a job, nor did I request Mr. Messina’s assistance in obtaining one."

Colorado Republicans want to make Romanoff's Washington job search a campaign issue in the Senate race.

"With all of the problems our nation is facing, the Obama administration chose to focus on business-as-usual political games," Norton said. "The back-room deals and ‘Chicago-style’ politics have to stop."

The Bennet campaign hasn't yet responded to a request for comment.
