KEY POINTS
  • President Donald Trump says he signed a national emergency declaration to build his proposed border wall "much faster" than he would otherwise be able to.
  • The action, which the president has threatened for weeks, has already sparked backlash from both Democrats and Republicans.
  • Trump will likely face legal challenges and legislative efforts to block the declaration.

President Donald Trump emerged from one political crisis Friday and immediately dove into another.

The president signed a spending and border security plan into law to keep the government running through Sept. 30, with only hours to spare before parts of the government shut down Saturday. Before he did so, Trump also declared a national emergency to repurpose funds from other parts of the government to build his proposed border wall without congressional approval.
