Trump's U.S. Mexico border wall

Last week Friday US president Donald Trump declared a national emergency to obtain funds for a U.S.-Mexico border wall. Trump made this declaration after Congress refused his request for $5.7 billion to build the wall he had promised during his 2016 election campaign. Some legal experts in the US say that Trump’s move could lead his opposition in Congress to challenge him through the courts by way of lawsuits. Today it was reported that California and New York would approach the federal court to sue Trump’s administration. President Trump’s declaration of a national emergency will allow him to have access to money from Congress to be used for other purposes for the construction of the Mexican border wall. The White House has claimed that Trump will have access to around $8 billion.To assist us on this topic we are joined on the line by • Prof. Patrick Bond, political economist • Prof. John Stremlau, international relations analyst • Thomas Gift, political analyst joining us from the University College London
