"In July, I was interviewing a senior administration official on Ambassador Wilson's report when he told me the trip was inspired by his wife, a CIA employee working on weapons of mass destruction. "

This statement is ambiguous, and could hold a clue. To whom does the phrase "when he told me" refer? Is it the senior administration official, or Ambassador Wilson?
