Two election watchdog groups are suing President Donald Trump's administration over his executive order seeking to overhaul the nation's elections.

Election officials, state attorneys general and legal experts say President Donald Trump's executive order seeking to reshape election processes throughout the U.S. will likely face legal challenges for violating the Constitution.

President Donald Trump’s executive order seeking broad changes to how elections are run in the U.S. is vast in scope and holds the potential to reorder the voting landscape across the country, even as it faces almost certain litigation.

President Donald Trump says he is suspending the security clearances of attorneys at a prominent law firm involved in launching since-discredited opposition research during the 2016 presidential campaign into any ties between the Republican candidate and Russia.

With Election Day 12 days away, efforts are already underway in courtrooms across the country to sow doubt over the outcome.

FILE - In this Oct. 5, 2020 file photo, the White House is shown Monday afternoon, Oct. 5, 2020, in Washington. Both sides are informed by the experience of the 2000 election, which was ultimately decided by the Supreme Court in Bush v. Gore. Thousands of volunteer lawyers are prepared to assist with Election Day operations and poll watching and other issues, Riemer said. A group called Lawyers for Trump, whose advisory board includes Texas Attorney General Ken Paxton and Trump attorney Rudy Giuliani, is recruiting retired lawyers and law students. But lawyers on both sides say they are preparing to be ready for much more than a fight on Twitter.

RALEIGH, N.C. – North Carolina election officials agreed Tuesday that mail-in absentee ballots returned this fall with deficient information can be fixed without forcing the voter to fill out a new blank ballot. Marc Elias, a Democratic lawyer who helped sue in North Carolina court to seek the changes and has worked on similar absentee ballot litigation elsewhere, praised the decision. The absentee ballot adjustments are part of a proposed joint settlement filed in Wake County court between the State Board of Elections and the alliance, a union-affiliated group. North Carolina is one of eight states with witness and or notary public requirements for absentee ballots, according to the Brennan Center for Justice. North Carolina state law usually demands two witnesses, but lawmakers reduced the requirement to one this year because people isolated due to at-risk health conditions may find it difficult to locate two.

Substantive change to voter access in multiple states all at once is rare, but this year, officials have pushed to make mail voting easier to help protect people from the coronavirus. Democrats say they’re trying to make sure every vote counts, and voting rights advocates are raising the alarm that the expansion of existing absentee and mail voting systems could create widespread disenfranchisement and discrimination unless done correctly. Much of voting rights advocates' litigation is aimed at lowering the absentee ballot rejection rates that have skyrocketed during the primaries. The flaw in each of those amendments is that it delegates administration to the states.”And in that administration, advocates and academics alike see discriminatory effects in mail voting systems. Here’s what’s at the heart of the suits, and what could change about the rules surrounding vote by mail.
