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. … 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. [Letter to DHS Secretary Markwayne Mullin led by Kelly, Gary Peters, Dick Durbin, Alex Padilla and Chuck Schumer and signed by 34 senators, demanding he substantiate his July 17 claim that 250,000 noncitizens were registered to vote in four states.]
