Time to threaten immediate impeachment for corruption.
In 1969, Abe Fortas became the first—and, to date, only—Supreme Court justice to resign under the threat of impeachment. Named to the court by President Lyndon Johnson in 1965, Fortas was forced to step down due to financial improprieties that involved him agreeing to act as a paid consultant to the family foundation of a man under investigation for securities fraud.
In addition to Samuel Chase, 14 other federal judges (who are appointed by the president and confirmed by the Senate) have been impeached over the course of American history, on charges ranging from drunkenness on the bench to accepting bribes. The first impeachment was in 1803 and the most recent was in 2010. Eight of the jurists were convicted by the Senate and removed from office, while three were acquitted and three resigned.
