Dozens of Republican convention delegates are hatching a new plan to block Donald Trump at this summer's party meetings, in what has become the most organized effort so far to stop the businessman from becoming the GOP presidential nominee. [...] Given the strife, a growing group of anti-Trump delegates is convinced that enough like-minded Republicans will band together in the next month to change party rules and allow delegates to vote for whomever they want at the convention, regardless of who won state caucuses or primaries.
Donald Trump on Saturday called efforts by a group of Republican convention delegates to prevent him from officially clinching the nomination "illegal" and "a hoax." Mr. Trump, speaking at a campaign rally in Las Vegas, devoted a hefty portion of his opening remarks to criticizing efforts to dislodge him. "First of all it's illegal. Second of all, you can't do it," he said. "You have a couple of guys that were badly defeated, and they're trying to organize maybe like a little bit of a delegate revolt."
