Washington (CNN) Former Ohio Gov. John Kasich said Tuesday that he doesn't currently see a path that would lead him to defeat President Donald Trump for the 2020 Republican presidential nomination.

Kasich, who ran against Trump in the 2016 Republican primary, told CNN's John Berman on "Anderson Cooper 360" that he doesn't see a path "right now," but added, "That doesn't mean there wouldn't be a path down the road."

"But right now, I don't see it," he said.

Now a CNN senior political commentator, the former governor said his full explanation for why he doesn't see a path is a "complicated, long answer" that can't be laid out "in a few seconds" on television.
