October 2nd, 1968 Johnson withdraws Fortas nomination, the day after Senate refused to end
I'll have more tomorrow. This proves that the filibuster has been around a long time and used by the GOP.
Update- From wikipedia: "In 1965, Lyndon Johnson persuaded Supreme Court Associate Justice Arthur Goldberg to resign his seat to become Ambassador to the United Nations. He then appointed his long time friend, Abe Fortas, to the court. Fortas was initially reluctant to give up his substantial salary, but he eventually accepted.
When Chief Justice Earl Warren announced his retirement in June 1968, Johnson nominated Fortas to replace Warren as Chief Justice."
