Arpaio lost his re-election bid for Maricopa County Sheriff in 2016.
He was convicted of federal contempt of court and then pardoned last year by President Donald Trump.
Arpaio has long said he had ambitions for other political office, but never filed to run for anything other than sheriff.
The Federal Election Commission website does not have a listing for an Arpaio Senate campaign
