Rep. Seth Moulton (D-Massachusetts) announced Friday that he is ending his quest for the 2020 Democratic presidential nomination after failing to gain significant support.

The announcement ends Moulton’s short bid for presidency. He ran on a campaign focused on foreign policy, national security and veterans affairs. Moulton was a Marine and served four tours in Iraq and was very open about his battles with post-traumatic stress disorder. 

Moulton said he is “so proud” of what his campaign had done.

He is the fourth Democrat to drop out of the race.
