Trump threatens government shutdown over wall funding

United States President Donald Trump threatened to shut down the federal government if the funding for the wall on the border with Mexico does not receive the support of the Democrats. The funding of some of the government agencies will expire on December 21.

"If we don’t have border security, we’ll shut down the government," he said after the meeting in the Oval Office with Democratic leaders from the Senate and the House, Chuck Schumer and Nancy Pelosi. A bipartisan agreement on the matter does not seem likely, Trump added.

The administration needs $5 billion to fund the building of the wall, which is among Trump's main campaign promises, while the Democrats are only ready to agree to $1.3 billion for border fencing and barriers.
