Democrats and voting advocacy groups have filed lawsuits against President Trump’s sweeping new executive order to limit mail-in voting ahead of this year’s midterm elections. “This is clearly an attempt for the president to pick his own voters,” says Arizona Secretary of State Adrian Fontes, who is legally challenging Trump’s order. Voting rights experts have decried the order as an unconstitutional attempt by Trump to seize control of election administration from the states and Congress. It directs the Department of Homeland Security to create a “state citizenship list” and the U.S. Postal Service to mail ballots only to “verified” voters.
