Unfortunately not true; Trump pardoned several of his allies pre-trial, shutting down the process down before convictions could be secured. This included, notably, a Mossad agent responsible for recruiting US military personnel as assets; Steve Bannon, who on top of everything else was facing fraud charges for all the money that disappeared from the border wall crowd funding scam; and Kenneth Kurson, who ran a pro-Trump "newspaper" owned by Kushner, who was facing charges for cyber stalking Trump opponents.
