Homeland Security Secretary Kirstjen Nielsen refused to denounce a white supremacist who was charged with murdering a woman during protest in Charlottesville, Virginia.

Nielsen was speaking to the Aspen Institute on Thursday when she was asked about President Trump’s contention that “both sides” were to blame for the violence at a neo-Nazi rally last year.

“I think what’s important about that conversation is, it’s not that one side is right and one side is wrong,” Nielsen said about the incident that left 32-year-old Heather Heyer dead and several others severely injured.

“Anybody that is advocating violence, we need to work to mitigate.”

White power groups were protesting the removal of Confederate statues on August 12, 2017, when James Fields Jr. allegedly drove his car into a group of counterprotesters.

Days after the killing, President Trump blamed “both sides” for the violence.

Trump also said there were “very fine people” on both sides.
