Imam Feisal Abdul Rauf's wife told The Associated Press on Monday that he was back in the U.S.
Daisy Khan declined to comment further. She said her husband planned to comment on the debate surrounding the planned $100 million center later this week.
She says he returned Sunday from a 15-day State Department-funded trip to the Gulf. The tour was intended to promote religious tolerance.
During his Middle East trip, Rauf mostly sidestepped questions surrounding the Islamic center location about two blocks from the site of the Sept. 11 attacks.
