Joe couldn't have been at Fox outting Valerie because Joe & valerie were in the phone booth at Brewster-jennings then forging Nigerien Uranium documents. It came out in the intelligence hearings that Joe claimed to have read the forgeries before the U.S. even received them. Fitz had planned to wind up his investigation a year ago but the Wilson fabrications forced Fitz to re-interview a number of witnesses. Keep that mouth moving Joe. Loose lips sink ships (maybe the good ship "Patrick Figerald").
