This is an excellent run down of ducking scandal through the BFEE history. Right back to Prescott Bush...

The “talking point” memo also is a classic example of how the neoconservatives have used rhetorical games since the early 1980s when they rose to power under Ronald Reagan and George H.W. Bush.
When people have come up with information that can cause the neocons trouble, the neocons have applied an approach called “controversializing” the accuser.
The process works whether that person is a federal prosecutor (as in the case of Iran-Contra independent counsel Lawrence Walsh), a member of Congress (as with Rep. Henry Gonzalez and his probe of George H.W. Bush’s secret aid to Iraq); a journalist (as with New York Times correspondent Raymond Bonner, who wrote about Central American death squads in the early 1980s); or a private citizen (like Wilson was when he questioned Bush’s use of the yellowcake allegations).
In 1991-92, for instance, Walsh – a lifelong Republican – closed in on the obstruction of justice that had surrounded the Iran-Contra scandal for five years. Walsh’s investigation broke through the White House cover-up when his staff discovered hidden notes belonging to former Defense Secretary Caspar Weinberger.
The notes made clear that there was widespread knowledge of the 1985 illegal arms shipments to Iran and that George Bush Sr. had been lying when he claimed that he was “not in the loop” on the covert Iranian shipments.
