Any federal, state or local representative (with the exclusion of the President and Vice President) who wants to hire security, should do it on their own dime.
They get paid by the taxpayer so is that really their dime? Or do you mean that should not use any monies they earn and receive from the taxpayer while in office to pay for security services? And if a request by the elected official for city and state funded escort and protection services, then the same as above applies. No one would leave the District of Colombia or is that Douglass Country or something to that effect they want to rename it now after the first black marshall of DC?
