September 29, 2026 - WASHINGTON, D.C. — U.S. Senators Alex Padilla (D-Calif.), Ranking Member of the Senate Rules Committee with jurisdiction over federal elections, Gary Peters (D-Mich.), Ranking Member of the Homeland Security and Governmental Affairs Committee, Senate Democratic Whip Dick Durbin (D-Ill.), Ranking Member of the Senate Judiciary Committee, and Senate Democratic Leader Chuck Schumer (D-N.Y.), led 30 of their Senate colleagues in demanding Department of Homeland Security (DHS) Secretary Markwayne Mullin immediately halt the Department’s efforts to assert federal control over, and undermine public trust in, the 2026 midterm elections. 

The Senators demanded information substantiating Mullin’s public claims about thousands of noncitizens who allegedly registered to vote, and called on DHS to rescind new election-related conditions on Federal Emergency Management Agency (FEMA) homeland security grants, release the full grant funding to states, and immediately end the alleged “Unlawful Voter Initiative” disclosed by a recent whistleblower.   

“We write to warn you against continued activities at the Department of Homeland Security (DHS) that seek to undermine the Constitutional authority of both Congress and states to administer elections and defy the directions of federal courts. As Secretary of Homeland Security, you have promoted the President’s conspiracy theories about our elections, pressured states to participate in illegal activities, and explicitly threatened to reduce grant funding and initiate criminal investigations for those states that do not comply with the Administration’s demands,” wrote the Senators.   

In their letter, the Senators raised concerns about Mullin’s unsupported claim that 250,000 noncitizens were registered to vote in four states and criticized DHS efforts to pressure states to provide sensitive voter roll information to be run through the Systematic Alien Verification for Entitlements (SAVE) program, despite the Administration’s acknowledgment of problems with the underlying data. The Senators also objected to new election-related conditions on FEMA’s Homeland Security Grant Program, which have been retroactively applied to previously awarded Fiscal Year 2025 funding and are threatening Fiscal Year 2026 funding. By threatening to withhold funding that communities rely on to prevent acts of terrorism and other threats, Mullin is putting Americans’ safety at risk for political leverage.  

The Senators also highlighted allegations from a federal whistleblower about an effort referred to as the “Unlawful Voter Initiative.” According to the whistleblower, U.S. Citizenship and Immigration Services (USCIS) personnel were allegedly directed to use sensitive, personally identifiable information and improperly access state voter registration websites to find non-citizen voters. The whistleblower also alleged that personnel were directed to create law enforcement records using incomplete and unverifiable data for potential referral to law enforcement.   

“The 2026 midterm elections are already underway. Your unsubstantiated allegations of noncitizen voter fraud, public recitation of unreliable data, and unwarranted conditioning of continued grant funding for state election security measures on compliance with politically motivated requests for voter data appear to be calculated efforts to undermine confidence in our elections and risks wrongly disenfranchising voters,” the Senators concluded.   

In addition to Padilla, Peters, Durbin, and Schumer, the letter was signed by Senators Angela Alsobrooks (D-Md.), Tammy Baldwin (D-Wis.), Richard Blumenthal (D-Conn.), Lisa Blunt Rochester (D-Del.), Chris Coons (D-Del.), Catherine Cortez Masto (D-Nev.), Tammy Duckworth (D-Ill.), John Fetterman (D-Pa.), Ruben Gallego (D-Ariz.), Maggie Hassan (D-N.H.), Martin Heinrich (D-N.M.), John Hickenlooper (D-Colo.), Tim Kaine (D-Va.), Mark Kelly (D-Ariz.), Andy Kim (D-N.J.), Angus King (I-Maine), Amy Klobuchar (D-Minn.), Ben Ray Luján (D-N.M.), Jeff Merkley (D-Ore.), Patty Murray (D-Wash.), Jack Reed (D-R.I.), Jacky Rosen (D-Nev.), Bernie Sanders (I-Vt.), Adam Schiff (D-Calif.), Elissa Slotkin (D-Mich.), Chris Van Hollen (D-Md.), Mark Warner (D-Va.), Raphael Warnock (D-Ga.), Elizabeth Warren (D-Mass.), and Ron Wyden (D-Ore.). 

Following receipt of the bombshell whistleblower disclosure, Padilla and Schumer demanded Mullin and USCIS Director Joseph B. Edlow immediately halt the “Unlawful Voter Initiative” and provide responses to Congress on its activities, and protect citizens who were erroneously flagged as “unlawful voters.” Last week, Padilla and Schiff sent a letter to California Attorney General Rob Bonta highlighting the concerning activities detailed by the DHS whistleblower disclosure and requested that Bonta investigate whether those actions violated California law. Last week, Padilla and Schumer led 16 members of the Senate Democratic Caucus to demand the DHS Office of Inspector General (OIG) immediately open an independent investigation into the wrongdoings detailed in the whistleblower’s disclosure. The whistleblower’s disclosure is also being cited in ongoing litigation, Virginia’s Attorney General is examining potential violations of Virginia state law, and Arizona’s Attorney General and Secretary of State are calling on Arizona’s U.S. Attorney to look into this alleged misuse of data by the federal government.
