(FILES) Outgoing First Lady Melania Trump listens as her husband outgoing US President Donald Trump addresses guests at Joint Base Andrews in Maryland on January 20, 2021. Extremely discreet in the White House and even more reserved since leaving Washington, Melania Trump is keeping observers guessing whether she will appear, however warily, on the campaign trail alongside her husband. Aloof and enigmatic, the Slovenian-born former model has been noticeably absent as husband Donald Trump makes his third bid for the White House.
