D.C.’s 2014 mayoral race jumped today from a three-way tango to a four-member field with the campaign announcement of Reta Jo Lewis, a former official in both the Clinton and Obama administrations.

Lewis, who recently left her job as “special representative for global intergovernmental affairs” under Secretary of State John Kerry, becomes the first candidate in the mayoral race who is not a member of the D.C. Council. She joins Councilmembers Muriel Bowser (Ward 2), Tommy Wells (Ward 6), and Jack Evans (Ward 2) in the run for next April’s Democratic Party primary, which effectively serves as the District’s general election. Mayor Vince Gray has not indicated if he plans to seek a second term.

But Lewis’ entry into the race is somewhat out of the blue. Just who is Reta Jo Lewis? She did not get back to an interview request earlier today, but her campaign biography describes her as a 35-year-resident of D.C. Before working for Kerry and former Secretary of State Hillary Rodham Clinton, she was high up at the U.S. Chamber of Commerce. In the 1990s, she served as a special assistant to President Bill Clinton.

And while Lewis’ background is full of experience at the federal level, she’s had a bit of District-level exposure, serving in 1991 as the chief of staff at the Department of Public Works. She also previously chaired the D.C. Commission on Women. Her campaign’s website, though, is light on details for now, though on it she states that she is running so “we can make Washington, D.C. the world-class city we deserve.”

Lewis’ biography suggests someone who is positioned to run as a John A. Wilson Building outsider, but she’s not completely alien to the levers of local power. According to records with D.C.’s Office of Campaign Finance, she has donated $2,700 to various local candidates over the years, including Adrian Fenty, Vincent Orange, Michael A. Brown, and one of her new rivals, Bowser.
