The federal investigation into Florida Rep. Matt Gaetz’s alleged sexual encounters with teenage girls is winding down and no charges are expected to be filed against the firebrand Republican congressman, a person familiar with the probe said Friday. Federal prosecutors and the FBI began investigating Gaetz in late 2020 during the Trump administration over potential sex trafficking crimes related to allegations he’d paid women for sex and traveled overseas on at least one occasion to parties attended by teenagers who were not yet 18.
