This is a complete list of United States senators during the 115th United States Congress listed by seniority, from January 3, 2017, to January 3, 2019. It is a historical listing and will contain people who have not served the entire two-year Congress should anyone resign, die, or be expelled.
The One Hundred Fifteenth United States Congress was a meeting of the legislative branch of the United States federal government, composed of the Senate and the House of Representatives. It met in Washington, D.C. from January 3, 2017, to January 3, 2019, during the final weeks of Barack Obama's presidency and the first two years of Donald Trump's presidency.
In this Congress, Bill Cassidy is the most junior senior senator. Jeff Sessions was the most senior junior senator at the start of this Congress, but resigned on February 8, 2017, to become United States Attorney General. Maria Cantwell became the most senior junior senator after Sessions's resignation.
William Morgan Cassidy is an American gastroenterologist and politician who is the senior United States Senator from Louisiana, serving since 2015. A member of the Republican Party, he previously served as a member of the U.S. House of Representatives and the Louisiana State Senate.
Jefferson Beauregard Sessions III is an American politician and lawyer who served as the 84th United States Attorney General from 2017 to 2018. A Republican, Sessions previously served as United States Senator from Alabama from 1997 to 2017, resigning from the position in order to serve in the Trump administration.
The United States Attorney General (A.G.) is the chief lawyer of the federal government of the United States, head of the United States Department of Justice per 28 U.S.C. § 503, and oversees all governmental legal affairs.
Order of service is based on the commencement of the senator's first term. Behind this is former service as a senator (only giving the senator seniority within his or her new incoming class), service as vice president, a House member, a cabinet secretary, or a governor of a state. The final factor is the population of the senator's state. [1] [2] [3] [4] [5]
The Vice President of the United States is the second-highest officer in the executive branch of the U.S. federal government, after the President of the United States, and ranks first in the presidential line of succession. The Vice President is also an officer in the legislative branch, as President of the Senate. In this capacity, the Vice President presides over Senate deliberations, but may not vote except to cast a tie-breaking vote. The Vice President also presides over joint sessions of Congress.
The United States House of Representatives is the lower chamber of the United States Congress, the Senate being the upper chamber. Together they compose the legislature of the United States.
In the United States, a governor serves as the chief executive officer and commander-in-chief in each of the fifty states and in the five permanently inhabited territories, functioning as both head of state and head of government therein. As such, governors are responsible for implementing state laws and overseeing the operation of the state executive branch. As state leaders, governors advance and pursue new and revised policies and programs using a variety of tools, among them executive orders, executive budgets, and legislative proposals and vetoes. Governors carry out their management and leadership responsibilities and objectives with the support and assistance of department and agency heads, many of whom they are empowered to appoint. A majority of governors have the authority to appoint state court judges as well, in most cases from a list of names submitted by a nominations committee.

The United States Senate is the upper chamber of the United States Congress, which along with the United States House of Representatives—the lower chamber—comprises the legislature of the United States. The Senate chamber is located in the north wing of the Capitol, in Washington, D.C.
United States senators are conventionally ranked by the length of their tenure in the Senate. The senator in each U.S. state with the longer time in office is known as the senior senator; the other is the junior senator. This convention has no official standing, though seniority confers several benefits, including preference in the choice of committee assignments and physical offices. When senators have been in office for the same length of time, a number of tiebreakers, including previous offices held, are used to determine seniority.
