The Biden administration refused to send a witness to testify at a Democrat-led Senate hearing about shutting down the detention facility at Guantanamo Bay on Tuesday as Republicans compared President Joe Biden’s efforts to shut down the Cuban prison to the chaotic U.S. withdrawal from Afghanistan.

Democratic Senate Judiciary Committee Chairman Dick Durbin lamented during his opening remarks that the Justice Department “is yet to bring its legal positions in line with the president’s goal of closing Guantanamo.” He said he was “disappointed” Biden and Attorney General Merrick Garland had not yet responded to his letters calling for the facility to be shut down, adding: “I’m disappointed that the administration declined to send a witness to testify at today’s hearing about how they are working to close Guantanamo.”
