John Kasich in May with an offer to make him the "most powerful vice president in history," The New York Times reported Tuesday.

Trump's oldest son, Donald Trump Jr., reached out to a Kasich adviser after the Ohio governor ended his own Republican presidential campaign, promising that if he accepted the vice presidency, Kasich would be in charge of domestic and foreign policy.

The adviser asked what Trump would be in charge of, the report said, and Trump Jr. responded: "Making America great again."

Kasich has refused to endorse Trump, the GOP's presidential nominee, for president, and won't speak at this week's Republican National Convention even though it's taking place in his home state.

He has said Trump shouldn't expect an endorsement anytime soon. 

"Unless I see a fundamental change in that approach, it’s really hard for me to do a merger," he said in May.
