Senate asking questions about CIA alleged secret detentions WASHINGTON, Dec. 14 (UPI) -- A U.S. Senate committee review of the CIA's alleged secret detention centers raises "critical questions" for U.S. intelligence operations, a lawmaker said. Dianne Feinstein" class="tpstyle">U.S. Sen. Dianne Feinstein, D-Calif., chairwoman of the Senate Intelligence Committee, said her panel released a 6,000-page report to the White House outlining a detention program that she said provides details about every detainee in CIA custody. The report is classified. "The report uncovers startling details about the CIA detention and interrogation program and raises critical questions about intelligence operations and oversight," she said in a statement. Feinstein said the CIA's alleged use of secret detention centers was a "terrible" mistake that may require some difficult oversight. The American Civil Liberties Union and Human Rights Watch were among those calling for the public release of the report. The ACLU said the CIA was running a "torture program" while Human Rights Watch called it part of an "illegal and destructive national policy." Sen. Saxby Chambliss, R-Ga., the top Republican on the committee, told National Public Radio the report "contains a number of significant errors and omissions about the history and the utility of the CIA's detention and interrogation program." The European Parliament passed a non-binding resolution in September to investigate whether the CIA had secret detention facilities in the region. The resolution states that Lithuania, Poland and Romania were called on in particular to encourage or open independent investigations.
