What a congressional majority can change

Democrats won Congress, CBS projects. ^{[1] [2]}

The White House describes Congress's fundamental powers as lawmaking, taxation, borrowing, and oversight. A majority therefore changes which party organizes the legislative agenda, but does not erase the separate powers of the other branches. ^[3]

The Justice Department's Office of Legal Counsel explains that Congress conducts executive-branch oversight through its houses and delegated committees, not through an unlimited power of individual members. That distinction matters for subpoenas, hearings and the evidentiary record behind investigations. ^[4]

Senate procedure supplies an important limit: ordinary legislation generally requires three-fifths to invoke cloture, while overriding a presidential veto requires two-thirds in each chamber. A majority can set priorities without guaranteeing enactment. ^{[3] [5]}

The change is not immediate: the Senate says the Constitution normally places the new Congress at noon January 3 in an odd-numbered year, unless law sets another time. Election results and the start of a congressional term are different milestones. ^[6]

The Senate says unfinished legislation from the previous two-year Congress generally expires and must be reintroduced, with treaties treated as an exception. The institutional transition therefore changes the legislative starting point as well as the timetable for committee and floor work. ^[6]
