A 25-year-old staffer for Republican presidential candidate Ben Carson died Tuesday in a car accident that also injured three campaign volunteers. Carson suspended his campaign for the remainder of the day on Tuesday and stayed with Braden Joplin at the Nebraska Medical Center’s trauma center. The campaign confirmed Tuesday evening that Joplin died as the result of his injuries. The Carson campaign released the statement, “Braden Joplin died following an auto accident on slick roads near Atlantic, Iowa. Three other passengers in the van were treated and released from a hospital in Atlantic, but Joplin’s injuries were severe, and he was brought to Nebraska Medical Center’s trauma center in critical condition for treatment.” Carson also cancelled Wednesday campaign events.
