The 5-4 ruling marks the first major high court decision on a Trump administration policy. It upholds the selective travel restrictions, which critics called a discriminatory "Muslim ban" but the administration argued was needed for security reasons. 

In a written statement, Trump called the ruling "a tremendous victory for the American People and the Constitution." As critics continued to decry the policy as "xenophobic," Trump described the court decision as "a moment of profound vindication following months of hysterical commentary from the media and Democratic politicians who refuse to do what it takes to secure our border and our country."
