A federal mail-in voting rule is at the center of ongoing legal battles in the nation's capital. The rule originated from an executive order issued by President Donald Trump, which aims to ensure citizenship verification and integrity in federal elections. The order directs the federal government to create a list of citizens using state data and limit mail-in ballots to those on the list.

The goal, according to administration leaders, is to preserve election integrity. Further details on the proposed rule and the legal battles surrounding it are available from national news sources, including Gray DC.
