An Obama-appointed federal judge on Tuesday struck down key parts of President Donald Trump’s executive order, prompting a stark warning from White House Deputy Chief of Staff Stephen Miller about the judiciary’s course.
U.S. District Judge Denise J. Casper ruled that major sections of Trump’s March 25, 2025, executive order, titled “Preserving and Protecting the Integrity of American Elections,” exceeded presidential authority and violated the Constitution’s separation of powers. Casper found that the order went beyond enforcing existing law and instead attempted to create or change election rules on its own.
“While the Constitution vests the President with ‘executive Power’ and commands him to ‘take Care that the Laws be faithfully executed’… it does not grant the President any specific powers over elections,” Casper wrote in the ruling. “As a result, the President ‘plays no direct role in the process’ of appointing electors, ‘nor does he have authority to control the state officials who do.'”
In response, Miller posted on social media that he hoped Supreme Court Chief Justice John Roberts “understands the path these rogue judges have charted for the judiciary.”
The chief justice serves as the institutional head of the federal judiciary, and while he does not exercise direct authority over lower-court judges, Millers reference to Roberts echoed broader conservative criticism that the Supreme Court has not moved aggressively enough to curb lower-court rulings blocking Trump administration policies.
Casper previously issued a preliminary injunction blocking key provisions of the order while the lawsuit played out in court. After more than a year of litigation, the judge on Tuesday largely sided with the plaintiff states.
The lawsuit was brought by 19 states challenging the order and was heard in the U.S. District Court for the District of Massachusetts.
California Attorney General Rob Bonta, one of the lead plaintiffs in the case, hailed the ruling as a victory for the states.
“We sued President Trump over his attempt to unilaterally impose voting restrictions across the country â and we won,” Bonta said. “Today, a federal district court ruled that every provision we challenged in the Executive Order is unlawful and reaffirmed that the power to regulate elections is reserved to the States and Congress.”
Casper’s ruling permanently blocks the administration from implementing provisions that would have required documentary proof of citizenship on the federal form, altered voting requirements for military and overseas voters, and threatened to withhold federal election-related funding from states that refused to adopt certain election rules, including not counting ballots received after Election Day.
Casper declared that sections of the order were “unconstitutional and void because they are ultra vires and violate the separation of powers under the .”
In addition to finding that the executive order violated the Constitution, Casper also concluded that key provisions of Trump’s order conflicted with federal statutes, including the National Voter Registration Act and the Uniformed and Overseas Citizens Absentee Voting Act.
Trump signed the order on March 25, 2025, arguing that stronger safeguards were necessary to ensure election integrity and public confidence in federal elections, alleging that state officials have failed to comply with and federal law.
The at the time described the directive as an effort to restore trust in elections and strengthen voter citizenship verification.
“Under the Constitution, must safeguard American elections in compliance with Federal laws that protect Americans voting rights and guard against dilution by illegal voting, discrimination, fraud, and other forms of malfeasance and error,” the executive order stated. “Yet the United States has not adequately enforced Federal election requirements that, for example,
