The Trump administration faces two federal lawsuits from leftwing groups over President Donald Trump‘s executive order requiring proof of U.S. citizenship to register to vote and directing states to reject mail ballots received after Election Day.

Filed on Monday in Washington, D.C., one suit comes from nonpartisan advocacy groups, including the League of United Latin American Citizens, Secure Families Initiative, and the Arizona Students’ Association. The other was brought by top Democratic organizations and party leaders, who argue the directive unlawfully overrides state and congressional authority over election rules.
