The Trump administration has asked the US Supreme Court to progress the President's plan to temporarily ban citizens from six mostly Muslim countries.
Department of Justice lawyers have asked the court to overturn a US Court of Appeals decision that had placed a freeze on President Trump's revised ban, Reuters reports.
Justice Department spokeswoman Sarah Isgur Flores said the administration was "confident that President Trump's executive order is well within his lawful authority to keep the nation safe and protect our communities from terrorism."
"The President is not required to admit people from countries that sponsor or shelter terrorism, until he determines that they can be properly vetted and do not pose a security risk to the United States," she said.
In order to decide whether to allow the travel ban, the nine Supreme Court justices must consider if Trump's harsh election campaign rhetoric can be presented as evidence the government's order intended to discriminate against Muslims.
Should the travel ban pass, citizens of Iran, Libya, Somalia, Sudan, Syria and Yemen would not be allowed to enter the US for 90 days while the government implements stricter visa screening.
