WASHINGTON (Reuters) - President Donald Trump threatened on Friday to close the U.S. southern border if Congress does not agree to provide $5 billion in taxpayer funds for his border wall, widening a dispute that has already closed portions of the federal government.
With "non-essential" operations at numerous agencies shut down for lack of funding and Congress adjourned until next week, Trump was in the White House firing off angry tweets.
