WASHINGTON (AP) — White House chief of staff Denis McDonough and two leading senators on national security reaffirmed their support for closing the U.S. detention center at Guantanamo Bay, Cuba, after visiting the facility on Friday.

In a joint statement issued by McDonough and Sens. Dianne Feinstein, D-Calif., and John McCain-R-Ariz., the officials said they appreciated the service of those in charge of the 166 terror suspects detained at Guantanamo. Feinstein is the chairwoman of the Senate Intelligence Committee and McCain is the top Republican on the Armed Services Committee.
