The White House announced a new order on Sunday banning almost all travel to the United States from seven countries, citing national security threats.
Most citizens of Chad, Iran, Libya, North Korea, Syria, Venezuela and Yemen will be banned indefinitely starting next month. Citizens of Iraq and some from Venezuela traveling to the United States will face restrictions or heightened security.
President Donald Trump's new proclamation covers most of the countries from his original travel ban. The original ban caused a flurry of airport protests and lawsuits. The United States Supreme Court is set to hear arguments about the ban's constitutionality on Oct. 10.
"As president, I must act to protect the security and interests of the United States and its people," Trump said in the proclamation. "I am committed to our ongoing efforts to engage those countries willing to cooperate, improve information-sharing and identity-management protocols and procedures, and address both terrorism-related and public-safety risks."
The new ban will take effect Oct. 18.
