As a presidential candidate, Barack Obama claimed "we need to fully repeal the Defense of Marriage Act," which says states are not required to recognize other states' same-sex marriages.
That was then. This week, the Obama administration is facing the ire of gay rights groups after it filed a brief in California federal court defending the Defense of Marriage Act and calling it a "valid exercise of Congress' power" that is saving taxpayers money.
The Defense of Marriage Act, or DOMA, was signed into law by President Clinton in 1996. It doesn't prohibit same-sex marriages; instead, it says that no state "shall be required" to honor same-sex marriages taking place elsewhere or any "right or claim arising from such relationship."
