Democrat Alexandria Ocasio-Cortez is planning to introduce a bill to Congress that would ban Donald Trump from declaring a national emergency to fund his border wall.
Bloomberg reported that Ms Ocasio-Cortez, also known by her initials AOC, will join with Democrat Joaquin Castro to block the move.
“If President Trump declares a national emergency to fund his border wall, I’m prepared to introduce a resolution to terminate the President’s emergency declaration,” Mr Castro said.
The National Emergencies Act gives Congress the authority to do so by enacting a joint resolution, Mr Castro said.
Mr Trump is set to sign off on a deal which won’t provide the $US5.8 billion he wants for his border wall but would prevent a government shutdown again.
However, he is planning to declare a national emergency in order to get the money.
