1554. Restricted Areas -- 18 U.S.C. 1752
Section 1752(a) also applies to any posted, cordoned off, or otherwise restricted area where the President is or will be temporarily visiting. This provides protection for the President during his/her travels without requiring advance formal designation. Cross reference in 18 U.S.C. § 1752(a)(3) and 18 U.S.C. § 1752(a)(4) makes those subsections applicable to restricted areas. However, 18 U.S.C. § 1752(a)(2) does not apply to temporary visit areas. See S.Rep. No. 91-1252, 91st Cong., 2d Sess. 2, 9, 11 (1970). This appears to reflect an accommodation with First Amendment considerations.
