Ohio Gov. John Kasich returned to the national spotlight this week with criticism for the GOP and President Trump, raising questions about the former Republican presidential candidate's political future. . . .
John Weaver, a longtime aide to the governor and an outspoken GOP critic of Trump, told The Hill that Kasich is not looking toward 2020 or having internal meetings to discuss the prospect. . . .
"The governor has said you root for the pilot of the plane you are on," Weaver said. "That doesn't mean you want the same pilot for the next leg."
"You want this pilot to land the plane safely and get the hell out of there."
