D.C. Mayor Muriel E. Bowser, Del. Eleanor Holmes Norton and 10 D.C. Council members endorsed Hillary Clinton for president ahead of the city’s June 14 Democratic primary, according to the Democratic front-runner’s campaign.

The announcement came as no surprise because many of the city’s top leaders had already publicly pledging their support for Clinton. Bowser has used her Twitter account to publicize local Clinton campaign events. And in September, council member Jack Evans (D-Ward 2) introduced Clinton at an event at Foundry United Methodist Church and promised that he and his three daughters would be voting for her.

Three of the city’s 13 council members have not endorsed Clinton: At-large council members Anita Bonds (D), David Grosso (I) and Elissa Silverman (I). Bonds chairs the D.C. Democratic Party and is remaining neutral in the primary.  Grosso and Silverman did not immediately respond to a request for comment.

“Hillary Clinton has long been a friend to the District, supporting full autonomy and voting representation in Congress,” D.C. Council Chairman Phil Mendelson said in a news release from the Clinton campaign. “She is also a proven national leader.”

The D.C. Democratic primary has 45 delegates up for grabs. Twenty delegates have already been pledged to Clinton. Early polling shows that  Sen. Bernie Sanders of Vermont could hit the 15 percent threshold needed to win at least a few of the remaining delegates.

Last week, the Clinton campaign announced a D.C. team that includes two figures from her national campaign and a third who was heavily involved in her string of victories across the South. The campaign said it will open two offices in the city Monday in the 1200 block of Pennsylvania Avenue SE and the 1900 block of M Street NW.

D.C. Republicans held their presidential primary in March.
