U.S. Rep. Henry Waxman endorsed Ted Lieu for his congressional seat Thursday after the Democratic state senator placed second in the primary election.
Lieu will face Republican Elan Carr in the Nov. 4 runoff.
Lieu was one of 10 Democrats on Tuesday's ballot. Waxman did not endorse in the primary.
Waxman's statement said, in part: "I endorse Ted Lieu because he will always work tirelessly to strengthen the middle class, make higher education more affordable, help workers save for retirement, and protect our privacy from intrusive NSA surveillance."
There are more registered Democrats than Republicans in the 33rd District, which includes the communities of Malibu, Santa Monica and Palos Verdes, and a large chunk of the West San Fernando Valley. However, Carr placed first in the primary with 21 percent of the vote.
When Waxman was re-elected in 2012, he fought off an unusually strong challenge from Bill Bloomfield, a former Republican who ran without a party preference. Bloomfield poured millions into his campaign and outspent Waxman by a 3-1 margin. Waxman won by an eight-point margin in the first election since the most recent round of redistricting.
Lieu easily raised more money than Carr in the primary campaign. In the most recent fundraising report, filed through May 14, Lieu had raised almost $846,000 to Carr's $389,000. Lieu had to spend money to distinguish himself among the nine other Democrats in the field, plus wild card candidate Marianne Williamson.
Lieu has represented the South Bay area in the Assembly and Senate since 2005. Carr is an L.A. County Assistant District Attorney and a military veteran.
Waxman was elected to Congress in 1974. He announced in January that he would not seek reelection.
