'He has been racist, he's been sexist, he's been Islamophobic, he has been anti-LGBTQ, I mean, there's a long list,' Clinton told the Atlantic Events Festival last week.
She also said there's "a lot to be concerned about" over Trump's Supreme Court appointee Brett Kavanaugh.
The former presidential candidate and Secretary of State from Chappaqua cited Trump's behavior in the wake of Charlottesville, Virginia, riots in 2017, which were provoked when a white supremacist group marched through the city to oppose the removal of a statue of Confederate war general Robert E. Lee.
Violence escalated when counter-protestors joined the march, leaving more than 30 people injured and killing one.
'I think he has thrown his lot in with many people and groups whose stated objection is white nationalism, white supremacy, how could you explain what he did and why after Charlottesville?" Clinton said.
Trump condemned the "hatred, bigotry, and violence on many sides." He later referred to "very fine people on both sides."
