Democrats won both chambers of Congress on Tuesday — and the first crisis of the new political order arrives before the winners even take their seats. The law that funds the United States federal government expires at the end of Friday, December 11, 2026. If the outgoing, Republican-led Congress does not pass a new funding law by then, a partial government shutdown begins on Saturday, December 12 — three weeks before the new Democratic Congress is sworn in on January 3, 2027. Australia's ABC News reported on November 4 that new funding bills are the top priority of the returning Congress, and that a lapse would be the fourth shutdown of President Donald Trump's second term.
The law that is running out
The government is currently funded by a stopgap law — formally a continuing resolution — called H.R. 6500, the Continuing Appropriations and Extensions Act, 2027. The House passed it 370 to 48 on September 1, and President Trump signed it on September 2 as Public Law 119-103. A stopgap keeps agencies running at the previous year's spending levels while Congress finishes the 12 regular full-year spending bills. That finishing work is barely started: as of November 3, the House had passed 3 of the 12 bills and the Senate had passed none, according to the Committee for a Responsible Federal Budget, although the House Appropriations Committee has advanced all 12 drafts. The stopgap does not only cover agency budgets — the National Flood Insurance Program and surface transportation extensions also end around the same date, according to the law firm Holland & Knight, and community health centre funding expires on December 31.
A 'lame duck' holds the pen
The weeks between an election and the swearing-in of a new Congress are called a lame-duck session, because many voting members are on their way out — including senators who lost on Tuesday, such as Susan Collins of Maine, who conceded to Democrat Troy Jackson, and Jon Husted of Ohio, who lost to Sherrod Brown. They keep their votes until January 3. Congress is expected to sit for about six or seven weeks from the week of November 9 until Christmas, with a break for Thanksgiving, PoliAlert reported on November 4. Attendance itself is a problem: Politico reported in October that Republican leaders worried some members would not bother returning to Washington, and retiring Senator Thom Tillis of North Carolina, asked about bipartisan deals in the lame duck, answered, 'I mean, why?'
Three options — and a veto pen
Holland & Knight, in an October 9 analysis, sets out the outgoing Congress's three options: pass an omnibus or several 'minibuses' — bundles of the 12 spending bills — for full-year funding; pass a shorter stopgap into January or March 2027; or combine the two. None of it is simple arithmetic. Most bills need 60 votes to pass the Senate, where Republicans hold 53 seats, so at least seven Democratic votes are required — Fox News's Chad Pergram made that point on October 1. And anything that passes can be vetoed by President Trump; overriding a veto takes two-thirds of both chambers. House Appropriations Chairman Tom Cole predicted on September 1, according to CBS News, that December would bring either a yearlong stopgap or a shutdown.
The election result changed who holds the stronger hand after January 3, and therefore which bill each side wants now. Pergram wrote before the vote that Republicans might push to fund the government through fall 2027 straight away, locking in a full year on terms written while they still hold Congress, rather than accept a short bill running into a Democratic-controlled year. Democrats, he wrote, would likely argue that voters had spoken and press for a short stopgap — which would let the new Democratic majorities write the full-year bills themselves in January, and set up an early-2027 clash with Trump, with a shutdown then if not in December. Both readings predate the result, but the incentives they describe are now live.
More than the budget is stuck in the same weeks
Funding is the first deadline, not the only unfinished business. The Trump administration has requested a historic $1.5 trillion for defence spending, which Senate Democrats called a nonstarter, and Congress must still pass the annual defence policy bill, which runs about $1.15 trillion, and the farm bill, which covers crop supports and food assistance. Expanded surveillance powers under the Foreign Intelligence Surveillance Act lapsed in June and have not been renewed. Republicans have also discussed a large emergency package with money for the Pentagon, for farmers hit by drought and low crop prices, and for disaster relief stalled for months — and, as of September, GOP senators were talking about money for the war with Iran through budget reconciliation, the special process that lets some bills pass the Senate with 51 votes instead of 60. Senate Majority Leader John Thune admitted even before the election that it would be 'difficult' in the lame duck; after January 3, Democrats control what reaches the Senate floor.
America has done this three times in a year
A December lapse would not be a novelty. The United States has had three funding lapses since October 2025: a 43-day shutdown from October 1 to November 12, 2025 — the longest on record when it ended; a brief partial shutdown that began on January 31, 2026 and ended when Trump signed a funding bill on February 3, according to the Associated Press; and a record 76-day Homeland Security shutdown that ended on April 30, 2026, according to NPR. There is also a direct precedent for this exact political shape: after Democrats won the House in 2018, the outgoing Congress failed to agree on funding and a then-record 35-day shutdown began on December 22, 2018 and ran into the new Congress until January 25, 2019.
What a shutdown would actually hit
If no law passes by the end of December 11, agencies covered by the 12 unfinished bills face a partial shutdown from December 12. Under the Antideficiency Act, agencies generally cannot spend money Congress has not approved, apart from limited work protecting life and property and programmes paid from permanent funds. In practical terms, as Bluebill's November 4 briefing put it, a shutdown would freeze federal paychecks and could disrupt programmes such as SNAP food aid, weeks before the new Congress arrives. Back pay for furloughed federal employees is set in statute, but it is paid only after Congress passes the bill that ends the lapse — and in the early-2026 Homeland Security shutdown, TSA airport workers were among those who missed paychecks while it lasted. For Punjabi diaspora families, the exposure is concrete: relatives on federal payrolls, households receiving SNAP, immigration and passport casework that slows when agencies close, and truckers whose work runs on federally funded highway programmes — the surface transportation extensions expire on the same December date.
Two clocks, not one: the debt limit is separate
The December 11 deadline is about spending bills, not about the federal borrowing limit — the two are often confused and run on separate tracks. On November 2, federal debt subject to the limit stood at $40.31 trillion against a statutory ceiling of $41.1 trillion, according to the Treasury's Daily Treasury Statement — roughly $797.7 billion of room, which forecasters expect to last into early 2027. The Federal Reserve also meets on December 8 and 9, two days before the funding deadline, so markets face a rate decision and a shutdown deadline in the same week. For investors, history is oddly calm: Carson Group found that across 22 shutdowns since 1976 the S&P 500 gained an average of 0.3 percent during them and 13 percent over the following 12 months, though individual episodes ranged from a 4.4 percent loss to a 10.3 percent gain — averages that describe the past and predict nothing about December.
What happens next
Members of Congress return to Washington on November 9, and the lame-duck session runs, with a Thanksgiving break, toward Christmas. Watch three things: whether leaders choose a full-year package or a short patch into January — the choice that decides whether the new Democratic Congress or the outgoing Republican one writes America's spending for 2027; whether at least seven Senate Democrats will supply the votes any bill needs; and the calendar itself — December 11 for funding, December 31 for health centre funding, and January 3, 2027, when the Congress voters chose on Tuesday finally takes office. If nothing is signed by the end of December 11, the lapse begins December 12, and the fourth shutdown of Trump's second term starts on a Saturday morning.
