Senator Kamala Harris of California has suspended her presidential campaign after months of slumping poll numbers, a dramatic comedown after her campaign began with significant promise.
Ms. Harris has informed staff and Democratic officials of her intent to drop out the presidential race, according to sources familiar with the matter, which comes after a upheaval among staff and disarray among her own allies.
The announcement is both dramatic and unexpected, perhaps the most sudden development to date in a Democratic presidential campaign where Ms. Harris began in the top tier.
