The law bans many actions on the United States Capitol Grounds and inside the Capitol Buildings. It defines four key words: act of physical violence (hurting or threatening people, or damaging property), dangerous weapon (items listed in a 1932 law and things that throw projectiles, daggers, dirks, stilettos, or knives with blades over three inches), explosives (as defined in 18 U.S.C. 841(d)), and firearm (as defined in 18 U.S.C. 921(3)). You must not block or misuse the roads on the Capitol Grounds, or use the roads south of Constitution Avenue and north of Independence Avenue to carry goods except to or from the Capitol on federal duty. Selling items, putting up signs, or asking for money is not allowed on the Grounds. Do not climb on or damage statues, seats, walls, fountains, plants, or turf. Unless allowed by Capitol Police Board rules, you cannot bring, use, fire, ignite, or move firearms, dangerous weapons, explosives, or incendiary devices there. You also must not forcefully enter or stay on the House floors, enter restricted areas or galleries without permission, disrupt official business, use loud threatening language to stop proceedings, block passage, commit violence, or parade, demonstrate, or picket inside the buildings. Members of Congress and their authorized staff or officers performing official duties are allowed to act as needed. Except as provided in section 5106, you may not hold processions or display flags or banners promoting a party or movement on the Grounds.

In subsection (a)(3), the words “section 841(d) of title 18” are substituted for “section 121(1) of title 50” because of the enactment of 18:ch. 39 and the repeal of the provisions classified to 50:121(1) by section 1102 and 1106(a) of the Organized Crime Control Act of 1970 (Public Law 91–452, 84 Stat. 952, 960). The plural form “explosives” is used because that is the term defined in 18:841(d). In subsection (a)(4), the words “section 921(3) of title 18” are substituted for “section 901(3) of title 15” because of the enactment of 18:ch. 44 and the repeal of the provisions classified to 15:901(3) by section 902 and 906 of the Omnibus Crime Control and Safe Streets Act of 1968 (Public Law 90–351, 82 Stat. 226, 234). In subsection (e)(1)(A), the plural “explosives” is used for consistency with the term defined in subsection (a)(3). In subclause (iii), the words “by any means” are omitted as unnecessary. In subsection (e)(2)(A), the words “unless authorized to do so pursuant to rules adopted, or authorization given, by that House” are substituted for “unless such person is authorized, pursuant to rules adopted by that House or pursuant to authorization given by that House, to enter or to remain upon such floor or in such cloakroom, lobby, or room” to eliminate unnecessary words.
