The White House has asked the US Supreme Court to reinstate a travel ban on people from majority Muslim countries.
The ban has been blocked by lower courts which have said that it is discriminatory.
Two emergency applications have now been filed by the government with the court’s nine justices that seek to overturn those lower court rulings.
The controversial ban has prompted protests and debate across the US.
“We have asked the Supreme Court to hear this important case and are confident that President Trump’s executive order is well within his lawful authority to keep the nation safe and protect our communities from terrorism,” said Justice Department spokeswoman Sarah Isgur Flores.
