Donald Trump won the Republican Party primary in Missouri, MSNBC reported early on Wednesday.

The close victory -- which was not projected until after 100 percent of the state precincts reported their votes, gave Trump four out of five victories in Tuesday night's primaries. Ohio Gov. John Kasich's home-state victory prevented a sweep by the real estate mogul.
