We do have a law that limits protests/harrassment of officials on public property passed in 2012 under the Kenyan. It was intended to stop the Teaparty from getting near him or public officials. It was called HR 347 Federal Restricted Buildings and Grounds Improvement Act. I remember because I complained to my Congress person and Virginia Foxx sent me a snarky letter about why it was necessary.
I remember that!!!!
They need to start enforcing it.
