 | | Congressional committees also have the power to compel testimony from unwilling witnesses and to cite for contempt of Congress witnesses who refuse to testify and for perjury those who give false testimony. |
 | | Additionally, there are non-voting "delegates" from the District of Columbia, American Samoa, Guam, Puerto Rico (known as "Resident Commissioner" and serving a double-length term) and the U.S. Virgin Islands. |
 | | The powers originally delegated to the Congress by the original version of the Constitution were supplemented by the post-Civil War amendmentss to the Constitution (Amendments 13, 14, and 15, each of which authorizes the Congress to enforce its provisions by appropriate legislation), and by the 16th Amendment, which authorizes an income tax. |
