If the buildings constituting temporary offices of the President or the President's staff or if a building the President is temporarily visiting is Federal property under the charge and control of the General Services Administration, and disruptive conduct occurs on such property, violators may also be prosecuted for violation of General Services Regulations promulgated pursuant to 40 U.S.C. § 318 found in 41 C.F.R. § 101-19.3. These regulations have been upheld as constitutional against attacks for vagueness and overbreadth. See United States v. Cassiagnol, 420 F.2d 868 (4th Cir.), cert. denied, 397 U.S. 1044 (1970); United States v. Sroka, 307 F. Supp. 400 (E.D.Wis. 1969); United States v. Akeson, 290 F. Supp. 212 (D.Colo. 1968).
