What is a universal injunction and how did the Supreme Court limit its use?

President Trump looks on during a news conference in the Brady Briefing Room of the White House on June 27, 2025, in Washington, DC. Trump claimed a "GIANT WIN" on his social media platfom on Friday after the Supreme Court curbed the power of lone federal judges to block executive actions.

Friday’s decision stems from President Trump’s executive order regarding birthright citizenship, but the Supreme Court focused on whether lower federal courts have the power to issue nationwide blocks.
