Trump’s rivals Ted Cruz, a US senator from Texas, and Marco Rubio, a US senator from Florida, emphasized their determination to remain in the race.
Cruz, 45, won his home state of Texas and neighboring Oklahoma, bolstering his argument he had the best chance to stop the brash billionaire. Rubio, favorite of the Republican establishment, was projected the winner in Minnesota, his first victory.
Clinton’s rival Bernie Sanders, a democratic socialist US senator from Vermont, also won his home state along with Colorado, Minnesota and Oklahoma and vowed to pursue the battle for the nomination in the 35 states yet to vote. He lost to Clinton in Massachusetts, a fifth state he had hoped to win.
