"I mean, look, the country's divided enough," he said to MSNBC's Chris Matthews. "People are hungering for an end to all this. The name-calling. The chaos. And you're the president, when you're putting things out like this ... Look Chris, I'm the governor of the 7th-largest state in the country. I got things that make me mad, get me upset. [But] I don't start putting out a list of people that are my enemies."

"I thought we got over that when Nixon left," Kasich continued.

Kasich, who could not seek reelection this year due to term limits, is a frequent critic of the president, whom he opposed in the 2016 GOP primary.

Earlier this year, he said that he had become "convinced" that the president is incapable of unifying the country. Kasich is thought to be considering a 2020 primary bid as a Republican.

“He’s not capable of being a unifier. In fact, I’ve become convinced he doesn’t know how to accept personal responsibility and always finds somebody else to blame,” Kasich told CNN in October.
