A federal judge has barred several government agencies from complying with an executive order from former President Trump that sought to make major changes to the federal elections process, including requiring proof of citizenship during voter registration. The judge ruled that the order violates the Constitution's separation of powers and threatens the fundamental right to vote.

Why it matters

This ruling is a significant victory for voting rights advocates who argued that Trump's order was a form of voter suppression that exceeded the president's authority. It preserves the integrity of federal elections by preventing the imposition of burdensome new requirements that could disenfranchise eligible voters.

The details

U.S. District Judge Colleen Kollar-Kotelly blocked two parts of Trump's executive order, including the requirement for federal agencies and the Defense Department to require proof of citizenship during voter registration. The Clinton-appointed judge wrote that upholding the Constitution's separation of powers in the election context is a matter of 'substantial importance' and that the right to vote is a 'fundamental political right' that must be protected.

  • On March 2026, former President Trump signed the executive order in question.
  • On January 31, 2026, Judge Kollar-Kotelly issued her 118-page ruling blocking parts of the order.

What they’re saying

“Upholding our Constitution's separation of powers in the election context is a matter of substantial importance.”

“The Supreme Court long ago recognized that the right to vote is a 'fundamental political right' because it is 'preservative of all rights.'”

What’s next

The Trump administration is expected to appeal the ruling, setting up a potential Supreme Court battle over the scope of presidential power in regulating federal elections.

The takeaway

This court decision reaffirms the fundamental importance of protecting voting rights and the careful balance of power between the federal government and states in administering elections. It serves as a check on attempts to impose new barriers to voter registration that could disproportionately disenfranchise certain groups.
