Donald Trump is prepared to shut down the government again if he does not get funding for his border wall, his chief of staff has said. The president is “willing to do whatever it takes” to push through the contentious $5.7bn (£4.3bn) project, Mick Mulvaney warned as hundreds of thousands of federal staff prepared to return to work. Mr Trump signed off a spending bill on Friday to reopen shuttered government departments until 15 February.
