A federal judge has temporarily blocked several aggressive measures taken by the Trump administration in recent days to pressure election officials across the United States ahead of the upcoming midterm elections.
In a temporary restraining order issued Friday evening, US District Judge Trina Thompson warned that the administration's actions could interfere with election administration and threaten the voting rights of eligible voters.
“Although defendants (the Trump administration) claim that these actions are intended to prevent illegal voting by noncitizens, they create a substantial risk of interfering with election administration and disenfranchising eligible voters,” Thompson wrote in her ruling.
Under the order, the Justice Department and the Department of Homeland Security (DHS) are prohibited from directing state election officials to segregate ballots, remove voters from registration lists, or suspend ballot processing while the order remains in effect.
Judge Thompson, who was appointed by former President Joe Biden, also barred the agencies from threatening election officials with criminal prosecution.
She made clear that the administration cannot threaten, intimidate, or pressure election officials into changing ballot-processing procedures based on claims that certain voters are ineligible to vote.
The ruling strongly criticized the administration's months-long efforts to threaten legal action against election officials, accusing them of failing to take sufficient measures to prevent illegal voting.
“When state and local government employees distribute, process, count, or otherwise administer the 2026 midterm elections in accordance with the law, they do not violate federal criminal law, even if a particular ballot belongs to a registered voter whom defendants claim is ineligible to vote,” Thompson wrote.
The judge further ordered the administration to notify the court of any search warrant applications, grand jury subpoenas, or other directives seeking election materials or ballots based on lists compiled by the administration alleging that certain individuals are ineligible to vote.
The temporary restraining order will remain in effect until November 16.
The lawsuit was filed in the US District Court for the Northern District of California by a coalition of labor unions and civil rights organizations, including the NAACP and the League of United Latin American Citizens (LULAC).
The plaintiffs allege that the administration's recent actions violate voting rights laws and constitute an unlawful intrusion into the constitutional authority of states to administer elections.
At the center of the administration's efforts is a controversial data-matching program led by the Department of Homeland Security. The program compares state voter registration lists with federal government records to identify suspected noncitizen voters.
However, election officials have questioned the reliability of the lists generated through the program, arguing that they incorrectly include many US citizens alongside individuals suspected of being noncitizens.
Several lawsuits filed in recent weeks have prompted judges across the country to closely examine the administration's data-matching practices.
The federal government's attempts to compel states to cooperate in preventing noncitizens from voting have repeatedly faced legal challenges, dealing setbacks to the Trump administration's efforts.
Despite the ongoing litigation, the Justice Department has continued to increase pressure on state election authorities. It has sent letters to 29 states and Washington, DC, threatening investigations and demanding that they preserve all records and voter data from the 2024 elections.
Federal law already requires election-related records to be preserved for 22 months following an election.
In California, the Justice Department also sued in an attempt to stop the counting of ballots cast by thousands of voters whom the federal government suspected might be noncitizens.
However, a federal appeals court rejected the administration's position. The US Court of Appeals for the Ninth Circuit ruled that the federal government has no authority to interfere with the states' procedures for verifying voters' citizenship.
