US shutdown begins as Senate fails to pass new budget

The US government has begun shutting down of many of its services after the Senate failed to agree on a new budget.

A bill to fund the federal government until 16 February did not receive the required 60 votes amid a bitter dispute over immigration and border security.

It is the first shutdown ever to happen while the same party, the Republicans, controls Congress and the White House.

The impasse will affect hundreds of thousands of federal workers, and the recriminations have already begun.

The White House accused Democrats of "[putting] politics above our national security, military families, vulnerable children, and our country's ability to serve all Americans".

But the leading Senate Democrat, Chuck Schumer, said President Trump had turned down two bipartisan compromise deals and "did not press his party in Congress".

The last government shutdown was in 2013, and lasted for 16 days.

What is a government shutdown?

As of 00:01 Saturday, many federal agencies are no longer open for business - although essential services will continue to run.

Most staff in the departments of housing, environment, education and commerce will stay at 
home. Half of workers in the treasury, health, defence and transportation departments will also not be going to work on Monday.

National parks and monuments could face closure, which provoked an angry public reaction during the last shutdown in 2013.

Visa and passport processing could also be delayed.

But essential services that protect "life or human property" will continue, including national security, postal services, air traffic control, inpatient medical services, emergency outpatient medicine, disaster assistance, prisons, taxation and electricity generation.

This could be a protracted, ugly fight

The game of chicken ended with a head-on crash.

Republicans are anxious to label this the "Schumer shutdown" and, essentially, they're right. Chuck Schumer and his fellow Democrats (with the help of a few Republicans) blocked a bill that would have kept the government open - at least temporarily.

Determining responsibility and apportioning blame, however, are two decidedly different endeavours.

Democrats will argue that they had a deal with the president on their bipartisan compromise that included immigration reform - only to have him back away during that fateful obscenity-laden Oval Office meeting last week. Republicans will frame this as liberals putting undocumented immigrant protections over military readiness and health insurance for poor kids.

The blame game began at midnight, and the winner has yet to be decided. Generally, the loser in these types of showdowns is the party entering the fight with the lowest popularity - bad news for Mr Trump and the Republicans.

The good news, for both sides, is that their political bases will be thrilled they are playing hardball. Midterm election years, like 2018, tend to encourage this kind of rally-the-base manoeuvres.

Now that the line has been crossed, this could become a protracted, ugly fight.

Why can the two sides not agree?

The main bone of contention has been Democrats' demands for more than 700,000 undocumented immigrants who entered the US as children to be protected from deportation.

These "Dreamers", as they are known, were granted temporary legal status under a programme established by former President Barack Obama.

In September, Mr Trump announced he was ending the programme and allowing Congress until March to come up with a replacement.

The Republican president and congressional conservatives have been using the issue as a bargaining chip in an attempt to wring concessions from Democrats.

Mr Trump wants funding for tough new border controls, including his proposed US-Mexico wall.

Republicans added a sweetener to the bill in the form of a six-year extension to a health insurance programme for children in lower-income families.

But Democrats want this programme extended permanently.
