Democratic Sen. Kamala Harris is expected to end her campaign for the Democratic presidential nomination, according to a campaign official.
Harris launched her campaign in front of 20,000 people at a chilly, outdoor event in January. The first woman and first black attorney general and U.S. senator in California's history, she was widely viewed as a candidate poised to excite the same segment of voters that sent Barack Obama to the White House.
She raised an impressive $12 million in the first three months of her campaign and quickly locked down major endorsements meant to show her dominance in her home state, which offers the biggest delegate haul in the Democratic primary contest.
