At least five women claim to have had consensual extramarital affairs with Clinton, while at least two women have accused him of sexual harassment, and one of rape.
Trump has used the former president as an avenue to attack his wife, Hillary Clinton, the Democratic primary front-runner.
After Hillary accused him of being a sexist, Trump said he “had no choice” but to bring up her husband’s past infidelities.
“She came out with the sexism which is so nonsense, but she’s playing that card, and then I hit her back, and I talked about her husband and the abuse of women and the tremendous abuse — no, it’s tremendous abuse, it’s tremendous abuse,” he said at a rally earlier this week.
The thrice-married billionaire businessman drew controversy in December when he said Hillary was “schlonged” in the 2008 Democratic primary.
