“After much thought I have decided to end my campaign for president today,” Chafee told the Democratic National Committee’s annual Women’s Leadership Forum.

Chafee’s announcement, coming just days after Jim Webb also withdrew, leaves Clinton with only two opponents: Bernie Sanders and Martin O’Malley. In addition, Vice President Biden announced Wednesday he would not enter the race.

A former governor and senator from Rhode Island, Chafee had trouble raising money and gaining traction in the Democratic race. He struggled in last week’s first Democratic debate.
