The Austin real estate developer at the heart of the federal investigation of Texas Attorney General Ken Paxton is facing federal criminal charges. FBI agents arrested 36-year-old Nate Paul on Thursday. The charges Paul faces haven't been disclosed. Paul and his company World Class have been under investigation since 2019. The Paxton investigation was prompted by a complaint from lawyers formerly employed in the attorney general's office who claimed Paxton misused his office by intervening in legal matters involving Paul.
