A federal judge in Boston on Tuesday made permanent a block on Trump's executive order requiring proof of citizenship to register to vote, handing the administration a significant legal defeat weeks before the midterm election cycle accelerates.
U.S. District Judge Denise Casper, nominated to the bench by Barack Obama, converted a year-old preliminary injunction into a permanent ban, ruling that the Constitution reserves election regulation authority to states and Congress, not the president. "The Constitution does not grant the President any specific powers over elections," she wrote. The ruling covers several pieces of Trump's first executive order on elections, including the citizenship verification requirement and a provision that would have cut off federal funding to states that refused to comply.
The White House did not take it quietly. The same day Casper issued her ruling, Trump abruptly canceled the expected signing of a bipartisan housing bill, announcing he will refuse to sign any legislation until Congress passes his proof-of-citizenship requirement for voting. He also renewed his call for Senate Republicans to eliminate the filibuster to clear the path for the SAVE Act.
The administration had already been pressing Congress precisely because the courts have been hostile to the executive-order approach. The SAVE Act, which stands for Safeguard American Voter Eligibility, passed the House on February 11 by a vote of 218 to 213, with only one Democrat, Texas Rep. Henry Cuellar, crossing the aisle. It died in the Senate on March 27, falling short of the 60 votes needed to break a filibuster. Republicans hold 53 seats, and not a single Democrat joined them. One Republican, Alaska Sen. Lisa Murkowski, voted against moving forward.
That legislative failure made Casper's permanent injunction more consequential than it would have been otherwise. With the SAVE Act stalled and the executive order now permanently blocked, the administration's pathway to requiring citizenship verification before 2026's November elections is effectively closed unless the Senate arithmetic changes or the Supreme Court steps in.
Trump's leverage play on the housing bill is a signal that he views this fight as central enough to hold unrelated legislation hostage. Whether that pressure moves Senate Democrats or breaks Murkowski-style Republican resistance is, for now, an open question.
A Popular Policy Blocked by an Unelected Judge
The ruling lands at a stark disconnect from public opinion. A March 2026 Economist/YouGov poll found 59 percent of Americans support requiring proof of citizenship to register to vote. A Gallup survey put the number at 83 percent, including 67 percent of Democrats and 84 percent of independents. The White House has cited those figures repeatedly to frame the SAVE Act not as a partisan play but as mainstream common sense blocked by Senate procedure and, now, by a Democratic appointee in Boston.
Critics of the ruling from the right point to a pattern: Obama- and Biden-appointed district judges issuing sweeping nationwide or broad injunctions against Trump election-integrity measures, each one arriving in time to shape the next election cycle. Casper's preliminary injunction came down roughly a year ago. Her permanent ruling lands in June of a midterm year, with primary season underway in several states. Supporters of the order argue that however one reads the polling, a single district court judge should not be the mechanism by which national election policy gets settled.
The administration's best remaining move is an appeal to the First Circuit, which could, in theory, reverse Casper before November. The Supreme Court is the longer shot but a real one, given its recent willingness to take up election-related cases. What Tuesday's ruling guarantees is that the 2026 elections will proceed without any federal citizenship verification requirement at the registration stage, barring an appellate reversal in the next few months. Trump's decision to make this a legislative hostage situation suggests he knows an appeal alone is unlikely to change that in time.
