Hillary Clinton has called Donald Trump supporters a "basket of deplorables," comments that sparked anger from her Republican rival for the White House and quickly went viral. The Democratic nominee for president was speaking at a fundraiser in New York last night when she said, "to just be grossly generalistic, you could put half of Trump's supporters into what I call the basket of deplorables." "The racist, sexist, homophobic, xenophobic, Islamophobic - you name it. And unfortunately there are people like that. And he has lifted them up." Speaking to gay rights supporters, she added that those people are "irredeemable, but thankfully they are not America." Trump struck back today, posting on Twitter: "Wow, Hillary Clinton was so insulting to my supporters, millions of amazing, hard working people. I think it will cost her at the Polls!" "Basket of Deplorables" quickly became a trending hashtag on Twitter on Saturday. There was even a mock account @TheDeplorables. Clinton also told the crowd at the "LGBT for Hillary" gala that other Trump supporters are people who feel let down by the government and the economy, and are "desperate for change." "Those are people we have to understand and empathize with as well," she said.
