Same-sex marriage legislation in the United States

In 1996, the United States Congress passed and President Bill Clinton signed Public Law 104–199, the Defense of Marriage Act (DOMA).

Section 3 of DOMA defines "marriage" and "spouse" for purposes of both federal law and any ruling, regulation, or interpretation by an administrative bureau or agency of the United States government.

[2] In United States v. Windsor, the Supreme Court was asked to determine the constitutionality of Section 3 of DOMA, which defines marriage for federal purposes as the union of a man and a woman.

Its sponsors described it as a way to clarify the federal government's response to Windsor and restore the ability of the a state to control the definition of marriage within its borders.

[7] In the 111th, 112th, 113th, 114th, and 117th Congresses, the Respect for Marriage Act (RFMA) was introduced by House and Senate Democrats to repeal DOMA.
