The Nevada Secretary of State's Office has received seven voter-related Department of Justice subpoenas from the FBI over the past three months, it confirmed to The Nevada Independent on Thursday. News of the subpoenas had not been previously reported. The office did not provide additional information. The subpoenas mark a dramatic escalation of the Trump administration's efforts to interfere in Nevada elections. The Trump administration had previously sued Nevada for its decision to not hand over an unredacted copy of its voter file, which includes voters' driver's license numbers and partial Social Security numbers.
