The U.S. Supreme Court on Tuesday upheld President Donald Trump's restriction on travel to the United States from a handful of Muslim-majority countries.
The 5-4 ruling marked a major victory for the administration, ending months of legal battles over a key part of Trump's immigration policy.
The administration has cited national security grounds as a reason for imposing the travel ban. Critics, however, blasted it as discriminatory against Muslims.
The ruling restricts entry to the United States from five Muslim-majority countries -- Iran, Libya, Somalia, Syria and Yemen -- plus North Korea and Venezuela.
Chad was included in the September 2017 executive order, but it was recently removed after meeting security requirements.
Trump called Tuesday's ruling "a tremendous victory for the American people and the Constitution."
"The Supreme Court has upheld the clear authority of the president to defend the national security of the United States," he said in a statement.
"In this era of worldwide terrorism and extremist movements bent on harming innocent civilians, we must properly vet those coming into our country."
