What Happens on January 3: The Oath, the Quorum and the Rules Package

For most of American history, the people you elected to Congress in November did not show up for work until more than a year later. Under the original constitutional calendar, a new Congress's term began on March 4, and its first regular session did not convene until the first Monday in December, thirteen months after the election. In between, the old Congress, including members who had just been voted out, came back after the election and kept legislating until March. George Norris, a Republican senator from Nebraska who spent years attacking that arrangement, thought it was absurd that defeated members could keep writing the nation's laws. The fix he championed became the Twentieth Amendment, ratified on January 23, 1933, in the middle of one of the worst lame-duck periods the country ever endured. It is the reason the Congress elected on November 3, 2026, will take office at noon on January 3, 2027.

In short: The Twentieth Amendment moved the start of each Congress to January 3 to shorten the time between an election and the new members taking power. On that first day, the Senate swears in its new members and keeps going, while the House starts from scratch: it confirms a quorum, elects a Speaker, takes the oath and adopts a new set of rules. Here is what happens, in order, and why each step matters.

The lame ducks who kept legislating

In American politics a "lame duck" is an official whose successor has already been chosen. Under the pre-1933 calendar, lame ducks were not a short-lived curiosity. After every election, a full session of Congress, the so-called short session, met from December until March 4, and it included every member who had lost in November.

Norris made the argument that this was undemocratic: a Congress that voters had just repudiated could still pass laws, and a newly elected one could not act until thirteen months after it was chosen. The Senate passed his amendment more than once in the 1920s, only to see it die in the House. It finally cleared both chambers in 1932.

Then history supplied the argument's best illustration. Franklin Roosevelt was elected president in November 1932 in the depths of the Depression. Under the old calendar he could not take office until March 4, 1933. Over that long winter the banking system came close to collapse, with runs on banks and states declaring bank holidays, while the outgoing administration and the incoming one could not agree on what to do. By the time Roosevelt was inaugurated, much of the country's banking system had shut its doors. The Twentieth Amendment had already been ratified by then, but it did not take effect for the presidency until 1937. The first new Congress to begin its term on January 3 was the one that convened in 1935.

What the amendment actually says

The text is short and practical. Section 1 ends the terms of the president and vice president at noon on January 20, and the terms of senators and representatives at noon on January 3. Section 2 says Congress shall assemble at least once every year, beginning at noon on January 3, "unless they shall by law appoint a different day." Other sections deal with what happens if a president-elect dies or has not qualified before Inauguration Day, a set of contingencies that have never been used in practice but were written carefully because the drafters could imagine them.

That clause allowing Congress to set a different day is used more often than people realize. Congress has sometimes passed a short law moving the first meeting of a session by a few days, especially when January 3 falls on an awkward date. Other times it simply meets on the third, whatever day of the week that is. In 2021 the new Congress convened on January 3, which was a Sunday.

The amendment also left the lame-duck session alive in a smaller form. Congress still usually returns after a November election to finish spending bills and other business before the new members arrive. The difference is that the lame-duck period now lasts about two months instead of four, and the newly elected majority takes over in early January instead of the following December.

The Senate: a body that never fully resets

On January 3, the two chambers begin very differently, because of a design choice the Constitution's framers made on purpose.

Senators serve six-year terms, staggered so that about a third of the seats are up in each election. That means two-thirds of the Senate carries over from one Congress to the next without interruption. The Senate has long treated itself as a continuing body. Its standing rules remain in force from Congress to Congress unless the Senate changes them, which is part of why the filibuster has been so hard to dislodge: there is no first-day moment when the rules automatically lapse.

On the first day, the vice president, as president of the Senate, or a senator presiding in that role, administers the oath to the newly elected and reelected senators. By custom, they come forward in small groups, each escorted down the aisle by the other senator from their state or by a former senator of their choosing. After the oath, they sign the official oath book. The Senate then adopts routine resolutions, notifies the House and the President that it has a quorum, and is ready for business. Party control of the chamber shapes who chairs committees and sets the agenda, but those changes come through resolutions adopted after the oaths rather than by a new set of rules.

The House: an assembly that starts from nothing

The House is the opposite. Every one of its 435 seats is up every two years, and by long precedent each House is a new body that must organize itself from scratch. Its rules do not carry over. Its officers do not carry over. Until the House acts, its members-elect are not yet members.

The first day in the House follows a sequence that has barely changed in generations. Here it is, step by step.

1. Call to order. At noon, the Clerk of the House from the previous Congress calls the members-elect to order. The Chaplain offers a prayer, and the members-elect recite the Pledge of Allegiance.
2. Quorum call. The Constitution says a majority of each House constitutes a quorum to do business. The Clerk calls a quorum to confirm that a majority of the members-elect whose credentials the states have certified are present.
3. Election of the Speaker. The parties nominate their candidates and the clerk calls the roll, with each member-elect naming his or her choice aloud. A candidate wins with a majority of those voting for a person by name. If nobody does, the roll is called again.
4. The Speaker's oath. The newly elected Speaker is sworn in by the Dean of the House, the member with the longest continuous service.
5. Everyone else's oath. The Speaker administers the oath to all the members-elect at once. They stand with their right hands raised and take the same oath set out in federal law: to support and defend the Constitution against all enemies, foreign and domestic, and to bear true faith and allegiance to it. Only then are they members.
6. Officers. The House elects the Clerk, the Sergeant at Arms, the Chief Administrative Officer and the Chaplain, usually by a single resolution offered by the majority.
7. Notifications. The House adopts resolutions telling the Senate that it has a quorum and has elected its Speaker and Clerk, and naming a committee to join one from the Senate in telling the President that Congress is assembled.
8. The rules. The House adopts its rules for the new Congress, usually the previous Congress's rules with a list of changes, in a single resolution.
9. Committees. In the following days, each party submits resolutions naming its members to committees, and the House adopts them.

Most of this takes a single afternoon. The obvious exception is step three, which has occasionally taken days; until it is finished, nothing after it can happen.

The oath, and the very first law

Article VI of the Constitution requires senators and representatives, along with state officials and federal officers, to be bound by an oath to support the Constitution. It does not give the wording. Congress supplied it, and the subject was important enough that the very first law Congress ever passed, signed by President Washington on June 1, 1789, was a statute about administering oaths. The oath members take today is longer than that original one. Its current wording was adopted in 1884, after Congress set aside the much stricter loyalty oath it had required of officeholders during and after the Civil War.

The group that raises its hands on the House floor is a little larger than 435. Alongside the voting members stand the delegates from the District of Columbia, Guam, the U.S. Virgin Islands, American Samoa and the Northern Mariana Islands, and the resident commissioner of Puerto Rico, who serves a four-year term. They take the same oath, sit on committees and can vote there, introduce bills and speak on the floor, but they cannot cast a vote on final passage of legislation. Their status is a recurring argument in the rules package itself: some majorities have let them vote in a procedure called the Committee of the Whole, where much amending happens, and others have taken that privilege away. More than four million Americans live in the places they represent, and for those Americans, a line in the rules package decides how much of a voice they have on the House floor.

The House oath is taken together, in one moment. In the Senate, senators take it in small groups at the front of the chamber. Afterward, in both chambers, many members restage the moment with their families for photographs, holding a Bible or another book of their choice. Those later ceremonies are for the cameras. The legally binding oath is the one taken on the floor.

Why the rules vote is the day's real business

Of all the steps on January 3, the adoption of the rules may matter most for what happens during the next two years. The rules decide how bills reach the floor, how much power the Speaker and the Rules Committee hold, what the minority can force a vote on, what budget restrictions apply to new legislation, how the chamber handles ethics complaints and how a Speaker can be removed.

Because each House starts fresh, the majority writes these rules on day one, and it can change almost anything by a simple majority vote. In practice, the package is negotiated within the majority party beforehand and adopted on a party-line vote. That makes the rules vote the first real test of whether a majority can hold together. It is also where factions that lost the leadership races try to win back influence through procedural changes.

The minority has almost no power to change the rules, but it can offer a motion to send the package back with instructions, and it gets an hour of debate. Its speeches on that day often preview the fights of the next two years.

A new majority's first afternoon

Democrats won the House and the Senate on November 3, 2026, and the new Congress will convene on January 3, 2027, under a Republican president in his second term. The first day will follow the sequence above. In the Senate, the new majority will be reflected in resolutions on committee ratios and leadership, and the chamber's standing rules will carry over unless senators vote to change them. In the House, the majority will elect a Speaker, adopt a rules package and seat its committees.

Here's the argument for paying attention to the dull parts of that day. Most coverage will focus on the Speaker vote and on the families in the gallery. The decisions that shape the next two years, though, will be in the rules resolution, which few people read and which will be adopted within hours of the oath. A majority that wants to protect members' ability to bring popular bills to the floor, or to keep strong ethics rules, or to limit the power of a few members to stall the chamber, will write those choices into that resolution. The citizens who care about those things will have the most influence before it is written, in November and December, when members-elect are still deciding what to ask for.

What you can do

• Get your incoming members' contact details now. Use the representative finder to find your House member and senators, with phone numbers and contact forms. Calls in December, while the rules are being drafted, reach staff who are still forming the office's positions.
• Follow the transition coverage. Our topic page on the new majority gathers reporting on the leadership races, the rules talks and the first bills the majority plans to bring up.
• Look at what the last Congress managed together. The common ground page lists bills both parties passed together, a reminder that a new majority's first months often include bipartisan work alongside the fights.
• Watch the floor once it opens. After the first day, the politics page tracks Congress's votes and bills, including the rules resolution itself.

George Norris spent more than a decade arguing that the people voters choose should take office as soon as practical, and that the people voters rejected should stop making law. He lived long enough to see the amendment change the rhythm of American government before he died in 1944. Every new Congress that has gathered in early January since 1935 follows his calendar, and the one that convenes in 2027 owes its start date to a senator from Nebraska who thought thirteen months was too long to wait.
