Senate Seniority
Senate Seniority List: 119th Congress
Source: https://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.
