Doctors at Bethesda Naval Hospital used an experimental new procedure in which painful memories are virtually zapped away by a pinpoint laser beam in order to make the 28 redactions to Rice’s brain.

According to White House sources, Rice now has no memory of any conversations about Osama bin Laden, Saddam Hussein, Pervez Musharraf, Richard Clarke or the unmanned Predator drone.

In addition, Rice can no longer recall anything that happened in the first nine months of the year 2001, the sources confirmed. “Her memory pretty much picks up at the point where she starts doing an amazing job to protect America from terrorism,” one source said.

White House spokesman McClellan denied that the 28 redactions were made to Rice’s brain in order to conceal embarrassing revelations that might otherwise come out in her congressional testimony. “In the two hours allotted for her testimony, it would have been impossible for Dr. Rice to tell everything she knows,” Mr. McClellan told reporters. “But now, thanks to this procedure, she knows virtually nothing.”

At Bethesda Naval Hospital, doctors who performed the brain-zapping procedure said that the first question they asked Rice when she regained consciousness was, “Who is the President of the United States?”

“She was unable to remember Dick Cheney’s name,” one doctor said. “That’s when we knew the procedure was a success.”
