Wynn was first elected to the House in 1992, and he served on the powerful Energy and Commerce Committee. The 56-year-old Wynn served in the Maryland House of Delegates and state Senate for a decade before coming to Capitol Hill.
It is unclear whether there will be a special since Gov. Martin O'Malley (D) doesn't necessarily have to declare a special election. Democratic insiders are still trying to figure out what will happen.
Update — The law firm that Wynn is joining is Dickstein Shapiro, according to a press release just sent out by his office.
Wynn claimed that his departure will allow Edwards, who was heavily favored in the November general election, to win a special election to fill his seat and thus go before voters on Election Day as an incumbent.
"It has been a great honor to serve as a member of Congress representing the wonderful people of the 4th District. However, it is time to move into another phase of my life and I am very excited to be joining such an outstanding firm,” Wynn said.
"My leaving early will also allow our Democratic nominee Donna Edwards the opportunity to successfully navigate a special election and be sworn in this summer. This will not only give her seniority in the incoming congressional class of ’09, but more importantly, will allow her to get off to a fast start in serving the citizens of our community. I offer her my best wishes and stand ready to assist in any way possible."
