The government shutdown enters its eighteenth day on Tuesday, becoming the joint-second longest in history.
It has now matched the 18 days the government was shut down for in 1978 over a dispute caused when president Jimmy Carter vetoed funding for a nuclear-powered aircraft carrier and public works projects he considered a waste of money.
Donald Trump is expected to tell Americans on Tuesday that the US is facing a “crisis” on its southern border, as the government enters an eighteenth day of shutdown over his controversial wall policy.
In a televised address from the Oval Office scheduled for 9pm (2am Wednesday GMT), the president will attempt to convince the public of the need for a steel barrier the length of the US border with Mexico.
A signature pledge of his presidential campaign, Mr Trump has seen Democrats reject government spending plans over his demand of $5.7bn (£4.5bn) to build the wall, leading to 800,000 public sector workers being furloughed without pay until the issue is resolved.
