Republican presidential hopeful Michele Bachmann's campaign manager, Ed Rollins, and his deputy are leaving their roles, Rollins said on Monday, adding he would remain in a senior advisory position.
"I have great affection for her. I'll do anything I can to help her," Rollins, a veteran of many political campaigns told CNN. "I just don't have the endurance to do 14-hour days, seven days a week anymore."
The story was first reported by Politico, which suggests friction between the candidate and her staff does not appear behind the decision.
Deputy campaign manager David Polyansky was also stepping down, said Rollins.
Bachmann spokeswoman Alice Stewart, who worked with Rollins on the Mike Huckabee campaign in 2007, said, "The plan all along has been to restructure things after the straw poll. Ed has - and will always be - a valuable part of the campaign. Given his health, now is the perfect time for Ed to move out of the strenuous day to day activities and into a senior advisor role. After a tremendous Straw Poll victory, we look forward to building the team as we move closer to the caucuses and primaries."
