Where dose one report hatch act violations?

Also, for those who may not be aware, the Hatch Act prohibits civil service employees from engaging in some kinds of political speech, especially trying to influence other's votes. It is intended to keep the civil service non-partisan.

The screenshot above may have come from a presidential directive but, as a former civil servant, I believe that the people who enacted that directive acted illegally. Hopefully a report would get this taken down at least and, possibly, lead to some punishment for those involved.
