In a statement to the Miami Herald, a Trump campaign spokesperson said that Hinchcliffe’s joke about Puerto Rico does not “reflect the views of President Trump or the campaign.”
Bullshit.
They didn't book him by accident. They booked him for one and only one reason - so that he'd say things that they expected would appeal to Trump's supporters.
Didn't he throw paper towels at the Puerto Ricans asking for help after their island was devastated? I'm pretty sure his thoughts are in line with this comedian.
Even if he wasn't a racist fuckwad on his own, he's of a generation of white New Yorkers for whom being racist against Puerto Ricans was sort of a universal minimum.
