Five former Colorado Republican Party chairs endorsed CD-6 Republican candidate Mike Coffman, Coffman's campaign announced Tuesday.

The five former chairs are Bob Martinez (2005-2007), Ted Halaby (2003-2005), Don Bain (1993-1997), Phil Win (1979-1981) and Carl Williams (1975-1976), the campaign said in a release.

“It’s not surprising that leaders of our party who are familiar with Mike’s record of working with the Republican party, and on behalf of conservative principles are supporting him in this race," said Coffman manager Dustin Zvonek in the release. "They have each expressed their belief that we must send the most qualified and best prepared candidate to serve us in the United States Congress.”

Coffman said in the release that he was "deeply honored" by the endorsements.
