Here are some updates from today.

• A federal appeals court unanimously rejected former President Donald Trump's claim that he is immune from prosecution for actions he took as president in his efforts to overturn the 2020 election. Trump is expected to appeal to the U.S. Supreme Court.

• Wisconsin Republicans introduced a bill to establish strict standards of what exactly constitutes an "address" on a witness certificate for mail-in ballots, as a heated legal battle over the issue continues in the courts.

• Black Louisiana voters asked to defend the state's new majority-Black congressional districts from a legal challenge alleging that the districts are racially gerrymandered.

  • These intervening voters were part of the group of plaintiffs that contested Louisiana's congressional map in 2022 for violating the Voting Rights Act. Those claims were successful and led to the redrawn map that is now being challenged for racial gerrymandering.

• The Republican National Committee and other Republican groups appealed a decision dismissing a right-wing challenge to New York’s new and expansive mail-in voting law.

• The Mississippi Libertarian Party sued over a state law allowing mail-in ballots postmarked on or before Election Day to be counted if they are received within five days of the election. This is the second lawsuit filed over the deadline in two weeks.

How should the Supreme Court apply Section 3 of the 14th Amendment? The answer depends on who you ask.

• Over the last few weeks dozens of amicus — or “friend-of-the-court” — briefs have been submitted by members of Congress, state officials, political organizations, professors and historians — all seeking to make their mark ahead of oral argument this week. Democracy Docket’s Ashley Cleaves breaks them down in her latest. Read now.
