Pete Buttigieg, the 38-year-old who rose from mayor of a midsize Indiana city to a serious presidential contender, officially suspended his campaign on Sunday evening.
"The truth is that the path has narrowed to a close," Buttigieg told a crowd in his hometown of South Bend, Ind., after an introduction by his husband, Chasten. "We have a responsibility to consider the effect of remaining in this race any further."
