A Pro-Hillary Clinton Super-PAC Just Launched a Devastating Ad Against Donald Trump

With the Democratic primary almost finished, pro-Hillary Clinton super-PAC Priorities USA released its first ad, set to start airing Wednesday in Ohio, Florida, Virginia, Nevada, Colorado, Iowa, and New Hampshire. Featuring an Ohio couple discussing their daughter with spina bifida, the ad highlights the time Donald Trump mocked New York Times reporter Serge Kovaleski for having a disability after the journalist debunked Trump's claim of seeing Muslims in New Jersey celebrating on 9/11.
