Pete Buttigieg, the 37-year-old former mayor of South Bend, Indiana, dropped out of the presidential race on Sunday, March 1.

       Buttigieg officially made the announcement at an event in South Bend, where he said "today is a moment of truth ... the truth is the path has narrowed to a close, for our candidacy, if not for our cause."

       Buttigieg added: "We have a responsibility to concede the effect of remaining in this race any further. Our goal has always been to help unify Americans to defeat Donald Trump and to win the era for our values."

       Buttigieg's run was historic. He is the first openly gay man to launch a competitive campaign for president, and he broke barriers by becoming the first gay candidate to earn primary delegates for a major party's presidential nomination.
