Lyndon Johnson met former Supreme Court Justice Abe Fortas when they were both working in Washington, D.C. in the late 30s. Then in 1948, Fortas helped Johnson win a highly contested Senate seat. Johnson viewed Fortas as a trusted advisor, so when a Supreme Court seat opened up during his presidency in 1965, it was not surprising that he nominated him as Associate Justice. On August 11, 1965, the Senate confirmed his nomination. When Chief Justice Earl Warren retired, President Johnson nominated his friend to replace him, but this time his appointment was vigorously opposed. Johnson withdrew the nomination (http://goo.gl/CWdprN). Justice Fortas served on the Supreme Court as an Associate Justice for 4 years.
On May 14, 1969, he resigned under a threat of impeachment after certain financial dealings (involving convicted financier Louis E. Wolfson) came to light. On April 5, 1982, he passed away. Learn more about the justice at http://goo.gl/832RPt and http://goo.gl/VW5Tv1.
