John Anthony Castro, a long-shot Republican presidential candidate vying to have former President Trump removed from the ballot over the 14th Amendment insurrection clause, was arrested on federal tax fraud charges Tuesday — a day after a federal judge in Nevada threw out one of his lawsuits aiming to bar Trump from running. 

Castro, 40, of Mansfield, Texas, was indicted on 33 counts of aiding and assisting in the preparation and presentation of a false and fraudulent return, U.S. Attorney for the Northern District of Texas Leigha Simonton announced on Wednesday. Court records show the indictment was filed under seal on Jan. 3.
