California Sen. Kamala Harris is dropping out of the presidential race, citing a lack of funds. She informed staff of her decision on a conference call and later sent an email to supporters, in which she wrote "my campaign for president simply doesn't have the financial resources we need to continue."
"I'm not a billionaire," she added. "I can't fund my own campaign. And as the campaign has gone on, it's become harder and harder to raise the money we need to compete."
