...The President then called the ruling "a tremendous victory for the American People and the Constitution" and said he felt vindicated.
"This ruling is also 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," Trump said.
This is the third version of the travel ban. It was issued in September -- after previous bans had ricocheted through the courts -- and restricts entry from seven countries to varying degrees: Iran, North Korea, Syria, Libya, Yemen, Somalia and Venezuela. Chad was originally on the list but it was recently removed after having met baseline security requirements.
Challengers, including the state of Hawaii, argued that the travel ban exceeded the President's authority under immigration law as well as the Constitution. They also used Trump's statements during the campaign, when he called for a ban on travel from all Muslim-majority countries, but Roberts dismissed those concerns.
"Plaintiffs argue that this President's words strike at fundamental standards of respect and tolerance, in violation of our constitutional tradition," Roberts wrote. "But the issue before us is not whether to denounce the statements. It is instead the significance of those statements in reviewing a Presidential directive, neutral on its face, addressing a matter within the core of executive responsibility. In doing so, we must consider not only the statements of a particular President, but also the authority of the Presidency itself."
Stephen Vladeck, CNN's Supreme Court analyst and a law professor at the University of Texas School of Law, called the ruling a "big win" for the White House.
"The Supreme Court has reaffirmed the President's sweeping statutory authority when it comes to deciding who may and who may not travel to the United States, authority that both President Trump and future presidents will surely rely upon to justify more aggressive immigration restrictions," Vladeck said.
However, Vladeck noted that this was the third version of the travel ban and the administration made significant changes in response to lower-court rulings invalidating the first two iterations, including one issued one week after Trump became president in January 2017.
