US congressional talks over a border security deal have stalled, raising the chances of another government shutdown.
Negotiators were hoping for a deal by Monday to give Congress time to pass legislation by Friday, when the federal funding agreement runs out.
They remain divided on how many undocumented immigrants can be detained and funding for President Trump’s promised border wall with Mexico.
The previous shutdown, lasting 35 days, was the longest in US history.
Hundreds of thousands of workers were furloughed while others in essential services, such as hospital care, air traffic control and law enforcement, worked without pay.
In the event of a shut down Federal agencies including the departments of Homeland Security, State, Agriculture and Commerce could lose access to money and begin to close down again, affecting about 800,000 federal employees, who would go unpaid.
Further more, essential services continue to operate, with workers being required to show up. Reports indicate that last time, some employees continued to work unpaid but many others called in sick.
