"So is it still possible that you could vote for Donald Trump?" Bash pressed.

"Very unlikely," Kasich responded, adding, "Too much water under the bridge."

And if Trump wins?

"Well, we'll see what happens if that happens," Kasich said. "Whoever is the president, if I can do something to help them in a constructive way, and something I agree on, absolutely."

Kasich will attend a bipartisan meeting Friday at the White House aimed at touting the benefits of the Pacific Rim trade agreement before later appearing at the White House daily briefing.

"Frankly, I welcome it," Kasich said of backlash to his decision to join the effort, speaking of putting the country over the party.

And while he's not pushing Trump in Ohio, a swing state where polling this week has indicated a tight race, Kasich said he would try to get Republicans to the polls in general.

"We're going to go help people get the vote out, obviously," Kasich said. "Get Republicans out to vote, period."

"We want to reelect Sen. [Rob] Portman, and we want to reelect people down-ticket," he said.
