(CNN) - Howard Wolfson, Hillary Clinton’s former communications director, will be a top strategist for New York City Mayor Michael Bloomberg's re-election effort.
Bloomberg, who was first elected as a Republican, is now a registered Independent.
"As a New Yorker, I am very excited at the prospect of helping the Mayor at this very critical time in our city's history," Wolfson wrote in an Tuesday e-mail. "It is quite clear to me that the mayor's strong record provides a compelling case for his reelection - and that he will provide the proven leadership we need to guide the city through the unprecedented fiscal challenges we face."
Wolfson, a former advisor to New York’s Democratic Party and a long-time Bloomberg critic, downplayed his earlier assessments of his boss as an “out-of-touch billionaire.”
“That was my evil twin,” he told NY1 Tuesday.
