During an exclusive interview with NY1 Tuesday, top Democratic strategist Howard Wolfson announced that he will be joining Mayor Michael Bloomberg's re-election campaign as a senior communications advisor.

"Around the time of the term limits extension, the mayor's team reached out to me and suggested I might be interested in coming on,'' Wolfson told NY1's Roma Torre. "I was supportive of the mayor and the more we got talking, the more I thought this was a great idea."

A lifelong Democrat, Wolfson repeatedly praises Bloomberg, saying the mayor is "somebody who governs by addition, not by subtraction."

Asked about some of the tough words he has had for the mayor in the past – including once calling him "an out-of-touch billionaire", Wolfson joked: "That was my evil twin."

Besides being Clinton's communications director in her presidential run, Wolfson served in the same capacity for Clinton's first Senate campaign in 2000, and her re-election campaign in 2006.

He also served as communications director for Charles Schumer's Senate race in 1998 and went on to become the executive director of the Democratic Congressional Campaign Committee.

Wolfson was the senior communications strategist for the Democratic National Committee in 2004, and several upstate congressional races, including Kirsten Gillibrand's upset win in 2006.
