Why the US government might shut down and what to know

Funding for the US government will be cut off at the end of Tuesday unless President Donald Trump’s Republican Party can agree with opposition Democrats on a way forward on a spending bill.

That could bring some – but not all – US government services to a temporary halt.

Although budget confrontations are common in US politics, this particular spending fight is especially tense, given that Trump has spent the last nine months drastically cutting down the size of the federal government.

Simply put: any shutdown will be the result of an inability of the two parties to come together and pass a bill funding government services into October and beyond.

The Republicans control both chambers of Congress, but in the Senate – or upper chamber – they are short of the 60 votes they need to pass a spending bill.

Democrats, therefore, have some leverage in this case. They refuse to back a bill introduced by Republicans that they say will make it harder for Americans to afford healthcare, and have made this standoff primarily about advancing their healthcare policy goals.

They are calling for an extension of tax credits that make health insurance cheaper for millions of Americans – which are set to expire – and for a reversal of cuts to Medicaid that have been made by Trump. They also oppose propose spending cuts to the Centers for Disease Control (CDC) and National Institutes of Health (NIH).

A stopgap bill was earlier passed in the House, or lower chamber, but is yet to clear the Senate.

If no deal is struck, at 00:01 EDT on Wednesday (05:01 BST), the US will have its first shutdown for nearly seven years.

The last time the government shuttered was at the end of 2018, during Trump’s first term. Both sides are making last-ditch efforts trying to avoid a repeat.

On Monday, Trump met all four congressional leaders – the top Democrats in the House and Senate as well as their Republican counterparts. But there was little progress, and both sides appear to have dug deeper into their positions.

At this point, prospects for some kind of government shutdown appear high, and Vice-President JD Vance said as much after Trump met the congressional leaders on Monday.

On the Republican side, Trump administration officials have been unwilling, so far, to offer any substantive concessions.

They appear to believe Democrats, as the side making demands in exchange for keeping the government open, will bear the brunt of the public’s blame – as they have in some past shutdowns.

Democrats, meanwhile, believe their push for preserving health-insurance subsidies is a popular one.

What is more, their congressional leaders provoked the ire of left-wing activists for backing down during the last budget bout in March. Many Democrats are itching for a bigger fight this time around – and funding the government is one of the only places where their party has some leverage.

What stands out about this current standoff is the position of the White House.

In the past, long shutdowns were usually seen as politically dangerous, hampering both voters’ everyday lives and the images of lawmakers and the President.

But this time around, the Trump administration appears more than happy to shutter large parts of the US government for an extended period. In fact, officials have threatened to use a shutdown to identify “non-essential” workers who could then be permanently let go.

Also, after previous shutdowns, government operations mostly returned to normal, with staff and spending levels largely going back to prior levels once the standoff is resolved.

Over the past nine months, however, the Trump administration has slashed spending and pushed workers out of their jobs, testing the boundaries of presidential power. A shutdown could allow the administration to accelerate its massive reductions.

Not all of government will shut down if Congress doesn’t pass a spending bill.

Border protection, in-hospital medical care, law enforcement and air-traffic control would be expected to continue to operate during the stoppage.

While Social Security and Medicare cheques would still be sent out, benefit verification and card issuance could stop.

Generally, in a shutdown, essential workers continue as normal – some of them without pay for the time being – but government employees deemed non-essential are temporarily put on unpaid leave. In the past, these workers have then been paid retrospectively.

That means that services like the food assistance programme, federally-funded pre-school, the issuing of student loans, food inspections, and operations at national parks are expected to be curtailed or closed.

There could also be travel delays if the stand-off drags on and unpaid workers stop showing up, and a prolonged shutdown could also have secondary impacts on the US economy.

Quite common over the last 50 years.

There were three during Trump’s first term, including the longest in history at 36 days, which ended in January 2019. That one was brought about by disagreements over funding a wall on the Mexico border.

The Congressional Budget Office (CBO) estimated that it reduced economic output by about $11bn, including $3bn that it never regained.

Fellow Republican Ronald Reagan oversaw eight shutdowns during his presidency in the 1980s – though all were relatively brief.

Shutdowns over budgets are almost unique to US politics.

Under the US system, the different branches of government have to reach an agreement on spending plans before they can become law.

In most countries, budget votes become votes of confidence in the government itself. But because the US has equal and often divided branches of government, that is not the case.
