Washington Post: NASA Administrator Michael D. Griffin held an unusual meeting with the staff of the inspector general who oversees his agency and then ordered that video recordings of the meeting be destroyed, a House panel said yesterday. In a letter to Griffin, the chairman of the Science and Technology subcommittee on investigations and oversight demanded an explanation from the NASA administrator and accused him of improperly trying to influence the watchdog office's decisions on what it should investigate. In addition, the letter from Rep. Brad Miller (D-N.C.) said the order to destroy the meeting tapes, which was issued by NASA's chief of staff, "appears on its face to be nothing less than the destruction of evidence." In a response yesterday, NASA spokesman David Mould said that the meeting was proper, and was a way for Griffin to discuss outstanding issues with the inspector general's staff and to express support for a strong watchdog office
