A former U.S. State Department aide jumped into the D.C. mayoral race Tuesday, joining three D.C. Council members with years more experience in local politics.

Reta Jo Lewis, who worked under former Secretary of State Hillary Clinton until May, will contend with Council members Jack Evans, Muriel Bowser and Tommy Wells in the Democratic primary April 1.

Current mayor and GW alumnus Vincent Gray has not yet confirmed his candidacy.

A 59-year-old Georgia native, Lewis moved to D.C. in 1978 and served briefly as chief of staff to the Department of Public Works, the Washington Post reported. She was a special assistant to President Bill Clinton before she worked as Hillary Clinton’s special representative for global intergovernmental affairs.

Lewis, an attorney who now lives in the NoMa neighborhood, served as director of outreach for President Barack Obama’s 2008 transition.

A campaign spokeswoman told the Post that Lewis, whose announcement online was meant for “friends and former colleagues,” will launch a listening tour around the District followed by a campaign kick-off at the end of the summer.

Lewis declined to describe her campaign platform to the Associated Press, but said she is certain she can attract enough contributions to win. She has contributed almost $3,000 to city campaigns, including those of former Mayor Adrian Fenty and former Council member Michael Brown.

The winner of the city’s Democratic primary has also won the mayor’s seat every year.
