Senate time

The 90th Congress was notable because for a period of 10 days (December 24, 1968 – January 3, 1969), it contained within the Senate, all 10 of the longest-serving senators in history until January 7, 2013, when Patrick Leahy surpassed Russell B. Long as the 10th longest-serving senator in history. This period stretched from the appointment of Ted Stevens of Alaska to fill a vacancy to the retirement of Carl Hayden of Arizona early the next year.

The 99th Congress was the period in which most people from this list were serving together (all but Hayden, Russell Jr., Warren, Eastland, and Magnuson).
