Calling someone a white supremacist is a very strong and personal attack, but McHugh does not hesitate to denounce Miller from what she knows of him and how she saw in him a kindred spirit when she was on a racist path.
"I would absolutely call him a white supremacist," she says. His driving ideology is "white supremacy and anti-immigration especially," she adds.
McHugh herself once followed the same hate as Miller. When she first moved to Washington, she dated a white nationalist and they and their friends would hang out in a home they dubbed "the house of hate."
She tweeted virulently racist and Islamophobic statements but says she was still having fun and a social life.
When she went to work for Breitbart, she says she became more isolated -- working long hours remotely by herself and that helped to make her susceptible to what she calls her "radicalization" by Miller and others.
"My world got more sealed off and I got much more intense. I got prideful, and I got angrier and angrier," she says. "Unless you stop, you know, objects in motion, stay in motion. It just gets worse."
