Joe Biden will soon start delivering a primary-night speech after winning Florida and Illinois. (Watch his remarks here.) Biden is hoping to pull off a sweep tonight once Arizona’s polls close in about 45 minutes. But Biden’s apparently decisive victories in Florida and Illinois have already intensified calls for Bernie Sanders to drop out of the race. Facebook Twitter 21m ago 00:55 Trump clinches Republican nomination Trump has officially secured the Republican presidential nomination after winning the Florida and Illinois primaries tonight. Trump has now been awarded more than the 1,276 delegates needed to win the nomination, as Joe Biden and Bernie Sanders continue to fight for the Democratic nomination. This was the earliest point in the primary calendar that Trump could have secured the nomination. The president did attract a few primary challengers, such as former congressman Joe Walsh and former Massachusetts governor Bill Weld, but none of them picked up any kind of signficant support among Republican voters. “Fueled by both our longtime supporters and the thousands of new voters that continue to join our movement, we are united and enthusiasm is on our side,” Republican National Committee chairwoman Ronna McDaniel said in a statement. “We have the strongest record of success, an unparalleled grassroots infrastructure, and are thrilled to have President Trump as our Party’s presumptive nominee once again.”
