When Is the New Congress Sworn In?
The new Congress is sworn in at noon on Sunday, January 3, 2027. That is the moment the 120th Congress begins and the members elected on November 3 take office — House members and senators elected to full terms alike — and it is only then that the Democrats who won both chambers actually take control of them.
The plain reality is the gap between the vote and the power. The Associated Press called the Senate for the Democrats late on election night and the House early Wednesday, and the result was a rout — but under the 20th Amendment the terms of the outgoing members end, and their successors' terms begin, at noon on January 3. Until that moment the current Republican Congress keeps full power, including members who lost their seats or retired. That stretch of roughly two months is the lame-duck period, and the old Congress can still pass laws and confirm nominees in it. We have already answered on the blog whether Chuck Schumer will lead the new Senate majority that takes over that day.
What the parties are doing with the wait is settling who will hold the gavels. Hakeem Jeffries is expected to be elected Speaker — the first Black Speaker in the House's history — and Schumer intends to seek the majority leader's post unopposed, States Newsroom reported. House Republicans, heading into the minority, are choosing between Steve Scalise and Jim Jordan after Speaker Mike Johnson decided to step down from leadership rather than lead the minority, with those elections expected in mid-November. Committee chairs and assignments are likewise being decided in closed-door party votes during the lame duck, before the new Congress formally organises.
"The terms of Senators and Representatives shall end at noon on the 3d day of January... and the terms of their successors shall then begin."
That line from the 20th Amendment states the common-sense principle plainly: an election decides who will govern next, not who governs today. The gap is deliberate — it gives states time to certify their results and winners time to prepare — and it used to be far longer. Before the amendment was ratified in 1933, new members did not take office until March 4, leaving defeated members in power for four months; the amendment cut that to two. The consequence in 2026 is that everything the incoming majority has promised — the investigations, the subpoenas, the checks on the Trump administration — cannot begin with gavels in hand until January 3, and anything Washington must do before then, including funding the government, runs through the Congress the voters just voted out. Which leaves one live question over the date itself: January 3, 2027 falls on a Sunday, so will this Congress sit on a Sunday, or move its first day?
The details that matter are these. A Sunday start is not a barrier — the 117th Congress convened on Sunday, January 3, 2021 without incident — but Congress has moved the day before, shifting a Saturday January 3 to January 6 in 2015 by passing a law, which the 20th Amendment allows. No law changing the 2027 date has been passed. Even if the sitting moved, the terms themselves would still change hands at noon on January 3; only the swearing-in would wait. On the day itself, the House elects its Speaker before any member is sworn in, the new Speaker then swears in the whole House at once, and in the Senate the Vice President swears in the senators. Winners of special elections are the exception to the January wait: senators elected to fill unexpired terms, in Ohio and Florida in 2026, can be seated as soon as their state certifies the result.
The matter rests where the Constitution put it, in the words of the 20th Amendment: the old terms end, and the new ones begin, "at noon on the 3d day of January."
