Republican National Committee chairman Reince Priebus on Sunday warned there could be consequences for former presidential candidates who don't endorse their party's nominee. . . .
"We're a private party. We're not a public entity. Those people need to get on board. And if they're thinking they're going to run again someday, I think that we're going to evaluate the process – of the nomination process and I don't think it's going to be that easy for them."
