Rep. Nancy Mace (R) proposes a resolution aimed at preventing race-based caucuses in the U.S. House of Representatives. Multiple outlets report that the measure would bar caucuses that organize membership primarily on racial grounds, which would effectively require the Congressional Black Caucus and similar groups to dissolve or alter their membership criteria to comply. The proposal is described as targeting the legal or policy basis that allows such caucuses to operate within House rules. Mace characterizes the existing system as promoting segregation, and argues that House membership structures should not be based on race. Other reported details focus on how the resolution’s language would affect not only the Congressional Black Caucus but also other House caucuses that qualify as race-based under the proposal. The reports indicate the resolution is intended to change how these caucuses are recognized or permitted under House procedures, rather than directly addressing individual members’ eligibility. The measure’s prospects depend on support within the House, where the resolution would require consideration and action according to standard legislative and chamber processes.
