Janice Kay Hahn (born March 30, 1952) is an American politician serving as a member of the Los Angeles County Board of Supervisors from the 4th district since 2016.

[3] In the general election, Hahn defeated Steve Napolitano to succeed Don Knabe to become the next Los Angeles County supervisor from the 4th district.

[7] Her uncle, Gordon Hahn, was a member of the California State Assembly and a Los Angeles City Councilman from the late 1940s to the early 1960s.

Hahn then won the Democratic nomination to succeed Harman, but lost the general election to Republican State Assemblyman Steven T. Kuykendall 49%-47%.

[13] After the Bush administration suggested it would intervene in the labor dispute by using government troops to operate the ports, Hahn urged non-intervention.

[citation needed] Hahn cites her efforts to clean up the Port of Los Angeles as one of her main accomplishments while on the City Council.

The 2006 Clean Air Action Plan, which she and Mayor Antonio Villaraigosa pushed forward, set a goal of reducing pollution by 45 percent within five years and shifted the movement of goods at the ports to off-peak traffic hours.

[citation needed] On the City Council, Hahn was a major proponent of gang prevention, intervention, and suppression programs.

[citation needed] Hahn ran for Lieutenant Governor of California in 2010 but was defeated in the Democratic primary by San Francisco Mayor Gavin Newsom, finishing second in a field of three candidates.

[citation needed] The Los Angeles County Federation of Labor, AFL–CIO, endorsed Hahn in March 2011, a move the Daily Breeze called "significant" because of the fundraising and get-out-the-vote power of the large organization.

[18] As of March 23, 2011, Hahn had received endorsements from Senator Dianne Feinstein, Los Angeles Mayor Antonio Villaraigosa, Los Angeles County Sheriff Lee Baca, California Assembly Speaker John A. Pérez, California State Senator Ted Lieu, Torrance Firefighters Association Local 1138, and other notable figures such as former LA Laker Earvin "Magic" Johnson and environmentalist and actor Ed Begley, Jr.[19] On April 25, 2011, Hahn secured the endorsement of the Los Angeles Times.

[20] On June 5, 2011, Hahn was officially endorsed by primary opponent Marcy Winograd, California State Controller John Chiang, Assemblyman Warren Furutani and Assemblywoman Betsy Butler, as well as the gun-control group Brady Campaign.

[citation needed] Hahn voted on Nov. 19, 2015, for HR 4038, legislation that would effectively halt the resettlement of refugees from Syria and Iraq to the United States.
