Donald Trump doubled down on his infamous negative remarks about Rosie O’Donnell during Monday’s presidential debate against Hillary Clinton, and many on Twitter were quick to respond to the Republican nominee’s controversial statements.

After Clinton called Trump out on sexist and misogynistic comments he’s reportedly made in the past — including calling women pigs and slobs, according to the Democratic nominee — Trump denied the claims, saying that he’s only made comments like that about O’Donnell.
