Arizona leaders are reacting to President Trump's executive order to create a nationwide list of verified eligible voters, which requires the Department of Homeland Security and Social Security Administration to identify eligible voters in each state. The order would prevent the U.S. Postal Service from sending absentee ballots to people not on state-approved voter lists and require ballots to be sent in secure, trackable envelopes with unique barcodes. However, top Democrats in Arizona have argued that this move is unconstitutional and violates the United States Constitution. Arizona Attorney General Kris Mayes and Governor Katie Hobbs have both voiced their disapproval of the order. The Constitution's "Elections Clause" gives Congress the power to regulate election regulations but does not mention any presidential authority over election administration.
