A growing group of legal advocacy organizations is expanding court challenges against President Donald Trump's voting executive orders ahead of the United States midterm elections. The groups say the orders go beyond presidential authority and could change how millions of Americans vote. The lawsuits focus on executive orders issued in 2025 and 2026 that seek to change voting rules across the country. Legal experts argue that the US Constitution gives states the main authority to manage elections. They say the new federal actions could interfere with that system. Several voting rights groups, former judges, election officials, and legal organizations have joined the court fights. They are asking federal courts to block the orders before the November elections. The legal cases center on new rules for mail voting. One executive order would allow the US Postal Service to introduce new requirements for election mail. Opponents say the changes came too close to the election and could prevent many ballots from arriving on time. A federal judge in Massachusetts ruled against the order in early September. The judge made an earlier temporary block permanent. The ruling said the planned changes could affect millions of people who vote by mail during the election season. The judge also said there was no evidence that widespread mail voting fraud justified the rushed changes. The decision kept the current mail voting process in place while the legal battle continues. The US Department of Justice quickly appealed the ruling to the Supreme Court. Government lawyers argued that the postal rules are reasonable and do not take control away from states. They said the lower court order could harm the federal government and election planning. The Supreme Court has been asked to decide whether the postal changes can take effect before the election. Voting rights organizations say the administration is trying to expand presidential power over elections. They argue that election rules have long been managed by state governments under existing law. Lawyers from multiple organizations are working together in federal courts across the country. Their lawsuits challenge both the voting orders and other actions they believe exceed presidential authority. The legal effort also includes former state and federal judges from different political backgrounds. They filed court briefs arguing that the executive orders conflict with constitutional limits on presidential power. Advocacy groups say bipartisan legal support is important because election law affects every voter, regardless of political party. The legal campaign has grown as the election gets closer. More organizations have added lawyers and staff to prepare for emergency court hearings before voting begins. A separate lawsuit filed by Democratic state attorneys general also challenges the postal voting rules. That case helped secure the temporary order that later became permanent. At the same time, new concerns have emerged about voter information. Voting rights groups say the Justice Department has requested sensitive voter data from several states. They argue that the requests could create a national voter database without clear legal authority. Legal teams in states including Oregon and California have challenged those requests in federal court. They say personal voter information should remain protected under state election laws. Civil rights organizations have also filed lawsuits over similar issues. They say they are defending voter privacy as well as voting access. Another issue involves claims about non-citizen voting. President Trump has repeatedly argued that non-citizen voting is a major election security problem. Voting rights experts say non-citizen voting is already illegal and documented cases remain very rare. The administration has also increased federal election monitoring plans. The Justice Department announced that about 1,000 lawyers could be deployed to observe voting across the country. Critics say such a large federal presence may create confusion or discourage some voters from participating. The administration says election monitoring helps enforce federal voting laws. Legal experts say courts will likely play a major role in deciding the limits of executive authority before Election Day. Several former Justice Department officials have joined public efforts supporting the lawsuits. They argue that protecting election administration is essential for public trust in democracy. A network of former department lawyers has also begun working with lawmakers, election experts, and the public to explain existing election laws and constitutional limits. Other former federal officials say independent legal organizations are filling an important role by challenging government actions through the courts. Many of the lawsuits are moving quickly because election deadlines are approaching. Judges are expected to hear additional emergency arguments in the coming weeks. Election officials across several states are also watching the court decisions closely. Any change to mail voting procedures could require updates to election operations before ballots are sent. With the midterm elections only weeks away, the legal battle over voting rules continues in federal courts and could reach additional Supreme Court review.
