WASHINGTON (AP) — Former Rhode Island Gov. Lincoln Chafee is ending his Democratic presidential campaign.

In prepared remarks before an appearance before the Democratic National Committee, Chafee said he is dropping out.

Chafee delivered a widely panned debate performance earlier this month. He has struggled to raise money and gain traction against Democrats Hillary Rodham Clinton and Bernie Sanders.

The former U.S. senator called himself a “block of granite” when it came to issues during the debate and has highlighted his opposition to the Iraq war.
