Rhode Island House Speaker Gordon Fox is resigning from his leadership post and will not run for re-election, he said Saturday, a day after federal and state authorities raided his Statehouse office and home as part of a criminal investigation that they would not detail.

“Because of the respect I have for all members of the House of Representatives, I am resigning as Speaker,” Fox said in a written statement emailed Saturday evening to reporters. “The process of governing must continue and the transition of leadership must be conducted in an orderly manner.”
