Melania Trump’s surprise speech has put Jeffrey Epstein back on the political agenda at an already difficult time for her husband, whose ceasefire agreement with Iran appears to be at risk of falling apart, while US lawmakers are raising the alarm over his mental stability.

"I am not Epstein's victim," the first lady claimed in a bizarre speech that appeared to get ahead of a potential story tying her with the late sex abuser.

First lady Melania Trump addressed the nation on Thursday afternoon to deny a friendship of any kind, with deceased sex predator Jeffrey Epstein.
