U.S. laws and Senate hearings on polygamy
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.
With the added nice touch of a prison sentence for bigamy! But you like that part.
