"You know, yeah," the Ohio governor told NBC's "Meet the Press" when asked if Trump owes the president an apology.

Kasich, who ended his own presidential bid in May and has not endorsed the Republican nominee, said he doesn't agree with questioning Obama's birthplace.

Kasich said the issue and the fact that it keeps getting raised reflects a "growing division and anger" between people in the country who are members of different parties and have different philosophies.

"That's what we ought to be alarmed by. There was tremendous hatred being directed at George W. Bush, you know, that he needed to be impeached and all these insane things," Kasich said.

"And that same anger has moved on to Barack Obama Barack Hussein ObamaTwitter investigating automated image previews over apparent algorithmic bias Donald Trump delivers promise for less interventions in foreign policy Rush Limbaugh encourages Senate to skip hearings for Trump's SCOTUS nominee MORE. And it's going to move on to whoever should win this election. We ought to be alarmed with the drift in this country away from what's best for our nation and not what's best for me as I, you know, vent my anger or frustration."

The country will never solve its problems if people spend all of their time "spewing anger," Kasich said.

"I mean, we have to be in a position of where we recognize people's problems and work to solve them," he said.

"And so I see this issue as one of a whole number of issues where people are saying, 'I'm in my silo. Don't bother me.' And it's not good for their children or for our nation."
