According to Time,
Bracing for the worst, Administration officials obtained from the Secret Service a list of all the times Abramoff entered the White House complex, and they scrambled to determine the reason for each visit. Bush aides are also trying to identify all the photos that may exist of the two men together. Abramoff attended Hanukkah and holiday events at the White House, according to an aide who has seen the list. Press secretary Scott McClellan said Abramoff might have attended large gatherings with Bush but added, “The President does not know him, nor does the President recall ever meeting him.”
Every so often during this Bush administration, I am reminded of the Soviet Union.
Of course, now we have Photoshop instead of airbrushes, so revising the photos should be easy.
