President Trump is expected to announce that he will use executive action to draw upon a variety of administration funding sources to help finance construction of his border wall, a White House official said.

The executive action is expected to include a national emergency declaration.

The official confirmed the President is set to announce the total amount to be in the range of $8 billion.

The official did not specify exactly where all of that money will come from and whether the executive action would withstand a court challenge, which could come from Democrats.
