Ohio Governor John Kasich took on Donald Trump on his home turf.

FOX's Tonya J. Powers reports from New York.

Ohio Governor John Kasich addressed the media here today in Midtown Manhattan, taking direct aim at Donald Trump in his own backyard.

He outlined reasons that Trump supporters should get behind him instead of someone he says is untethered and "becomes unmoored". Kasich took issue with several of Trump's talking points, including his stance on Nato and the Muslim community, saying he believes Trump is simply not prepared to be president.

Kasich is campaigning in New York, where voters go to the polls on April 19.
