It's looking like the Republican National Committee might have secured Donald Trump's promise not to make an independent run for president if he's denied the Republican nomination. He's got a Thursday afternoon press conference scheduled, as well as a meeting with Reince Priebus, the Republican National Committee chairman. Sources tell AP it's about a deal. While neither side would publicly confirm late Wednesday that an agreement had been reached, Trump has hinted in recent days the GOP lobbying was beginning to work.
