(FILES) Former US President and Republican presidential candidate Donald Trump (L) and former First Lady Melania Trump arrive to vote in Florida's primary election at a polling station at the Morton and Barbara Mandel Recreation Center in Palm Beach, Florida, on March 19, 2024. 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.
