"I'm a voter in California and I have voted for Hillary Clinton for president of the United States and proud to endorse her for that position," she said.
The California Democrat and superdelegate, who did not formally endorse in the 2008 Democratic primary, has praised Sen. Bernie Sanders' primary campaign and the excitement the Vermont senator has generated among younger voters.

In an interview with ABC News' George Stephanopoulos today, Pelosi said she believes Sanders will be a constructive force in 2016 before the Democratic convention in Philadelphia.
ABC News estimates that Hillary Clinton secured enough delegates to clinch the Democratic nomination for president Monday night, based on new Associated Press counting of superdelegate endorsements, making Clinton the first woman to clinch a major party's presidential nomination.
