Trump added that he thinks his father should declare the emergency to "build the wall with the United States military because that’s what people in this country want.”

The president in recent weeks has threatened to declare a national emergency to build the wall if Congress won't approve funding for it. Lawmakers, however, have predicted that the move would prompt immediate legal challenges.

Trump's demand for the construction of a border wall was at the center of a partial government shutdown that began Dec. 22 and lasted more than a month, finally ending on Friday when Trump signed a bill to fund the government for three weeks.

Trump had previously refused to sign a bill to fund the government that didn't include $5.7 billion for a wall. Democrats vowed throughout the shutdown not to approve any funding for a wall.

The bill Trump signed Friday didn't include money for a wall, and he has indicated that he may declare a national emergency if Congress doesn't approve wall funding within the next three weeks.
