Story highlights Ohio Gov. John Kasich declined to endorse his party's presumptive presidential nominee Donald Trump

In an interview with Fox News on Thursday, Kasich described a recent phone call between Trump and him

(CNN) Ohio Gov. John Kasich said Thursday he still isn't ready to endorse presumptive Republican nominee Donald Trump.

"Why would I feel compelled to support someone whose positions I kind of fundamentally disagree with?" he told Fox News.

Kasich suspended his own run for the White House a little more than a month ago and has since declined from endorsing Trump, decrying the divisiveness and "name-calling" he says has been a part of the campaign.

"Mr. Trump called me and said, 'What are you going to do to support me?' and I said, 'We're like two companies. We have a difference vision, a different value system, and a different objective,' So its pretty hard to put that together," Kasich told Fox News' Bill Hemmer, referencing a conversation that occurred a couple weeks ago.

The Republican National Convention is set to be held in Kasich's own state of Ohio in just over a month. But when asked if its possible he could walk into the convention in Cleveland and still not endorse Trump, Kasich said, "Absolutely. Of course."
