Seth Moulton became the third candidate in the last eight days who have announced the end of their campaigns for the Democratic presidential nomination. Moulton, a U.S. Representative from Massachusetts, told the New York Times Friday he would not continue his bid for the nomination.

Moulton didin’t garner the polling or the unique donor requirements to get into any of the debates. So far 10 presidential hopefuls have met the requirements for the fall debates, thinning a nearly two-dozen candidate field.

While he was in Iowa, Moulton highlighted his personal backstory as a veteran who served four tours in Iraq, and promote public service while criticizing the president.

He came to Iowa City in March, as he was still considering his candidacy, to speak to the Veterans Legal Association at the University of Iowa College of Law.

Moulton has represented Massachusetts in the U.S. House since 2015. He formerly served as an infantry platoon commander in the Marine Corps, where he served four tours in Iraq beginning in 2001. Veterans affairs has emerged as a central issue for him.
