A n emerging rift between Melania Trump and Hunter Biden escalated Thursday when the son of former President Joe Biden issued an expletive-laden response to the first lady's demand that he apologize for an allegation he made about her alleged prior ties to convicted sex trafficker Jeffrey Epstein.

Hunter Biden claimed in an interview that sex offender Jeffrey Epstein introduced the first lady to her now-husband, Donald Trump, which the Trumps say is false.

President Donald Trump confirmed Thursday morning that Melania Trump’s attorneys are threatening legal action against Hunter Biden, saying he told her to “go forward.”
