Actually, it is very hard for a public figure to win a libel suit. And since the suit is a fact and the allegations are a part of the suit, there is no way Trump could sue for libel because someone repeats the allegations.
Trump already sued the lead plaintiff in the case for defamation. Trump lost and had to pay the woman’s attorney almost $800,000.
Trump has never won a defamation lawsuit because the truth is an absolute defense.
