On Saturday, CNN's S.E. Cupp interviewed reformed white supremacist Christian Picciolini.
As the former leader of a Chicago gang of racist skinheads, Picciolini was an organizer in the rightwing hate movement before reforming at age 22 and later leading a group set on deprogramming young extremists.
Picciolini said that violent extremists are likely to act when they are called to do so by President Donald Trump.
"When somebody with power gives them words that back up with what they believe, spreads conspiracy theories and gives them some sort of agency, there's a certain subsegment of these extremists groups that will act," he said. "Most extremists may just be extremists vocally, and in ideological terms, but there's also a group of people within every extremist group that will take action based on the words that they hear. Now that hate is being normalized, they feel they are in power."
Picciolini reacted to a clip of Trump calling himself a nationalist.
"It was loud like a bullhorn to me," he said. "I didn't hear a dog whistle."
