The "Equality in the Halls of Congress Act" aims to expand representation within the National Statuary Hall Collection by permitting U.S. territories and commonwealths to contribute statues. Specifically, it authorizes American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, the Commonwealth of Puerto Rico, and the United States Virgin Islands to provide and furnish statues, adhering to the same specifications as those provided by states. This legislation amends existing law (2 U.S.C. 2132) to include these five entities within the definition of "State" for the purposes of the collection. The bill mandates the Architect of the Capitol to take necessary measures to acquire these statues and implement the Act, thereby promoting greater inclusivity in this historical display.
