The parents of Sen. John Ensign, R-Nev., pitched in to help Democrat Harry Reid, the state’s senior senator, in his 2010 re-election battle.

Mike and Sharon Ensign, who made waves in July after admitting to giving $96,000 to Ensign’s mistress and her family, each gave the maximum $4,800 in contributions to Reid’s campaign committee in the September, the Senate Majority Leader’s campaign disclosed in its third quarter fundraising report.

Despite being on opposite sides of the partisan divide, Reid and Ensign have an unofficial non-aggression pact, and Reid has remained silent on his colleague’s admission over the summer that he had carried on an affair with Cynthia Hampton, a staffer and wife of one of his top aides, Doug Hampton.
