Presidential candidate Lincoln Chafee, who is polling at the bottom of the Democratic field, said on Thursday he would "address my future in the campaign" in a speech on Friday.

Chafee, a former Rhode Island governor, said on Twitter he would discuss the subject in a speech to the Democratic National Committee's Women's Leadership Forum in Washington on Friday morning.

"I'll address my future in the campaign there," Chafee tweeted.

Chafee barely registers in opinion polls. Former Secretary of State Hillary Clinton is the front-runner in the field of four candidates for the Democratic nomination for the November 2016 election.

The Chafee campaign did not immediately respond to a request for comment.
