In a major ruling on Friday, the Supreme Court limited the ability of judges to block President Trump’s policies nationwide, including his order to end birthright citizenship.
Mr. Trump immediately cheered the ruling, while critics have decried it as a fundamental threat to the rule of law.
Adam Liptak, who covers the Supreme Court for The New York Times, explains how the ruling redefines the role of the courts, just when the White House is aggressively testing the limits of its power.
