From Government Executive:

With some key primary elections at the state level occurring in the coming weeks, the Trump administration has begun notifying employees they can no longer use paid administrative leave to vote.

The reminder, so far sent out at least to various agencies within the Agriculture Department, complies with an executive order President Trump signed on his first day in office. That order revoked a bevy of previously issued presidential actions, including an order President Biden signed early in his term to allow the leave category for federal employees looking to vote.
