United States president, Donald Trump is set to declare a national emergency and take other executive action to allow the construction of his long-promised Mexico border wall.

This is coming after bipartisan congressional negotiations approved less than a quarter of the $5.7 billion Trump wanted to start building more than 200 miles of wall at the country’s southern border.

The approved amount is just enough to construct over 55 miles of new barriers and fencing at the border.

White House Press Secretary, Sarah Sanders said Trump would sign the bill and take other executive action including a national emergency to enable him deliver ‘on his promise to build the wall, protect the border and secure our great country’.

However, declaring a national emergency at the southern border would prompt a legal fight which would test the powers of all three branches of the country’s government.
