Non-voting members of the United States House of Representatives

Non-voting members of the United States House of Representatives (called either delegates or resident commissioner, in the case of Puerto Rico) are representatives of their territory in the House of Representatives, who do not have a right to vote on legislation in the full House but nevertheless have floor privileges and are able to participate in certain other House functions. Non-voting members may introduce legislation and may vote in a House committee of which they are a member.
