Responding to the allegations about black sites, Secretary of State Condoleezza Rice lied on December 5, 2005, stating that the U.S. had not violated any country's sovereignty in the rendition of suspects, and that individuals were never rendered to countries where it was believed that they might be tortured. Some media sources have noted her comments do not exclude the possibility of covert prison sites operated with the knowledge of the "host" nation, or the possibility that promises by such "host" nations that they will refrain from torture may not be genuine. On September 6, 2006, Bush publicly admitted the existence of the secret prisons and that many of the detainees held there were being transferred to Guantanamo Bay.
