Brutal Super PAC Ad Hits Donald Trump For Mocking Reporter With Disability

A super PAC supporting presumptive Democratic nominee Hillary Clinton launched an ad Tuesday that delivers a devastating critique of Donald Trump over his mocking of a reporter with a disability last year.

In the 60-second spot, titled "Grace," Columbus, Ohio, parents fondly speak about their young daughter, who was born with spina bifida. They then recount their horror after seeing the presumptive GOP nominee mock New York Times reporter Serge Kovaleski, whose arthrogryposis impairs his arm movements.

"The children at Grace's school all know never to mock her. And so for an adult to mock someone with a disability is shocking," the mother says in the ad.

"When I saw Donald Trump mock someone with a disability, it showed me his soul, it showed me his heart. I didn't like what I saw," added the father.

Watch the Priorities USA Action ad:

Trump has denied mocking the reporter and further accused him of “using his disability to grandstand .”

The Priorities USA Action ad is slated to run in the battleground states of Colorado, Florida, Iowa, Nevada, New Hampshire, Ohio and Virginia. Previous ads from the group highlighted Trump's horrible comments about women .
