Earlier questions about the use of federal facilities (for example< the White House) did not generate answers that were specific to use of government property but were either closed without an answer or devolved into a discussion of the permissible actions of government employees.
So to sharpen the question: Can a federal employee, exclusive of the President and Vice President, use government property (telephones, computers, computer networks, printers, offices, etc) for political campaign activities?
If the Hatch Act does not apply to the use of government property for political campaign activities, is there some other act that does?
