Senate Seniority List: 114th Congress

Source: http://www.senate.gov/artandhistory/history/resources/pdf/chronlist.pdf

Senate rank is first determined by the length of consecutive service in the Senate. For senators who entered the Senate on the same day, several tie-breaking procedures determine seniority. In order of precedence, these factors are: previous Senate service, service as the vice president, previous House service; service in the Cabinet, service as a state governor. If a tie still exists, senators are ranked according to the population of their state at the time of swearing in.

* Phil Gramm resigned early, effective Nov. 30, 2002, so that Cornyn could move into his office suite and begin organizing his staff. Cornyn did not, however, gain seniority, owing to a 1980 Rules Committee policy established by Senator Pell that no longer gave seniority to senators who entered Congress early for the purpose of gaining advantageous office space.
