"You know, just to be grossly generalist, you could put half of Trump’s supporters into what I call the basket of deplorables," Clinton, the Democratic presidential nominee, said Friday night at a fundraiser.

Obama's tweet was a response to Republican nominee Mitt Romney's "47 percent" gaffe, in which he said nearly half of Americans were so dependent on the government that they were likely to vote for Obama "no matter what."
