Senator Chuck Schumer is the voice you hear posing the questions to former Deputy Attorney General of the United States.
According to Wikipedia:
In early January 2006, the New York Times, as part of their investigation into alleged domestic surveillance by the National Security Agency, reported that Comey, who was Acting Attorney General during the March 2004 surgical hospitalization of John Ashcroft, refused to “certify” central aspects of the NSA program at that time. The certification was required under existing White House procedures to continue the program. After Comey’s refusal, the newspaper reported, Andrew H. Card Jr., White House Chief of Staff, and Alberto R. Gonzales, then White House counsel and now Attorney General, made an emergency visit to the George Washington University Hospital, to attempt to win approval directly from Ashcroft for the program.Wow. Someone actually gave some information while testifying. He also named a few more names and gave his version that can be checked with those named. Things are not looking good for Alberto Gonzales.
