Federal ban on first-cousin marriages

This bill would amend Section 7 of title 1, U.S. Code. It would replace every occurrence of the phrase "2 individuals" in that section with a longer phrase. The new phrase would say the two individuals must not be related by blood (consanguinity) or by marriage (affinity) within the degree of first cousin. If enacted, this would bar federal recognition of marriages between first cousins or between people related by marriage within that degree. The text does not set an effective date, penalties, or funding changes.
