Full speech, context is everything.
Clinton — in the midst of championing her husband’s 1994 crime legislation — did use the term "superpredator" when referring to "gangs of kids." She did not specifically label superpredators as African-American, but the context of her speech and her subsequent apology decades later suggests it was a reasonable inference.
Priebus’ claim is accurate, but needs some clarification, so for that reason we rate his statement Mostly True.
The full context of this incident does link children and superpredators, but nowhere in the speech does she directly label African-American youth this way.
However, backlash from this speech has followed Clinton into this year’s election. Two Black Lives Matter
activists confronted Clinton at a private fundraiser in February, telling the candidate she owes black people an apology.
One day after this confrontation, Clinton released a
statement to the
Washington Post’s Jonathan Capehart, expressing regret for her word choice.
"Looking back, I shouldn't have used those words, and I wouldn't use them today," she said.
If you want to use that as evidence that she's a racist, and thus worse than Trump, then we don't live in the same reality.
