Donald Trump has knocked out all of his rivals for the Republican nomination, but you wouldn't know it by looking at his campaign schedule.

The real estate developer is setting out on his biggest campaign swing since becoming the de facto nominee — and he's still focused on primary states. New Mexico, California, Montana aren't exactly general election battlegrounds, but they're all places where Trump is going this week.

Donald Trump likes to tout his popularity among conservative Christians, who make up a key voting base within the Republican Party. But even with Trump as the de facto nominee, some evangelicals say they're unsure about voting for him — as a matter of conscience.

It may be too late for a man identified as a white nationalist leader to be removed from a list of Trump delegates, an official in the California secretary of state's office told NPR.

"The Trump campaign did not reach out to our office about removing William Johnson's name as a delegate until Tuesday, May 10 — which is past the statutory deadline to submit delegate lists to the Secretary of State's office," Press Secretary Sam Mahood said in a statement.
