U.S. Republican front-runner Donald Trump warned on Wednesday of riots if he is denied the party's presidential nomination after a string of primary election victories.
The New York billionaire scored big wins in Florida, Illinois and North Carolina on Tuesday which brought him closer to the 1,237 delegates he needs to win the nomination.
But one loss — in the crucial state of Ohio — left the door open for those in the party trying to stop Trump from becoming the Republican nominee for the Nov. 8 election.
