Fewer than 2,000 votes separated Trump, the billionaire businessman, from Texas Sen. Ted Cruz out of about 925,000 that had been counted with nearly all precincts reporting early Wednesday. Former Secretary of State Clinton led Vermont Sen. Bernie Sanders by a similarly close margin out of more than 623,000 votes counted.
The Associated Press has not declared a winner in either race.
Under Missouri law, candidates can request a recount if they lose by less than one-half of a percentage point. Both races fall within that margin.
Missouri was the only of Tuesday’s five primary states where the races were that close.
