U.S. laws and Senate hearings on polygamy<quoted text>
Is Polygamy illegal?
Federal law prohibits polygamy in the territories. Federal law also does not provide legal recognition of polygamy. It defines marriage as one man, and one woman.
U.S. laws concerning polygamy:
Gregory Brower, the Arizona U.S. Attorney, said during a Senate hearing in 2008-JUL that there is no federal law against polygamy. He commented that the federal government has a number of traditional resources at its disposal to investigate polygamists, including FBI, Alcohol, Tobacco and Firearms, IRS, and other inspectors.
However, polygamy is illegal in all 50 states under state laws.
