(CNN) Former Rhode Island Gov. Lincoln Chafee ended his long-shot bid for the 2016 Democratic presidential nomination, he announced Friday.

"As you know, I have been campaigning on a platform of Prosperity Through Peace," Chafee said at the DNC's annual Women's Leadership Forum in Washington. "But after much thought I have decided to end my campaign for president today. I would like to take this opportunity one last time to advocate for a chance be given to peace."

The Democrat declared his presidential campaign in June, shortly after announcing that he had formed an exploratory committee.

One of the reasons Chafee decided to drop out now: Hillary Clinton had "a good week," he said, one where former Virginia Sen. Jim Webb dropped out of the race, Vice President Joe Biden declined to run and she withstood hours of testimony on Capitol Hill.

"Obviously it was a good week for Secretary Clinton," Chafee told reporters after his speech. "She did well in the debates and then Senator Webb got out, Vice President Biden declined to join the race, she did well in the Benghazi hearing and Gov. Chafee got out of the race."
