Arizona Democratic Senators Mark Kelly and Ruben Gallego are calling for the immediate termination of a Trump administration investigation into the state's 2020 election results.

The senators sent a letter Thursday to newly appointed Department of Homeland Security Secretary Markwayne Mullin demanding an end to the federal probe. The lawmakers also shared their request with acting Immigration officials, though the full scope of the investigation's involvement across agencies remains unclear.

The investigation appears to be examining Arizona's 2020 election processes and results, though specific details about the probe's objectives and timeline have not been publicly disclosed by federal authorities.

The senators' intervention comes as the Trump administration has initiated various reviews of election-related matters across multiple states. Arizona's election results in 2020 were subject to multiple recounts and legal challenges, all of which confirmed the original outcomes.

Neither the Department of Homeland Security nor Immigration and Customs Enforcement has publicly responded to the senators' demands or provided details about the investigation's status or expected duration.
