NBC News is reporting that the Obama administration will file a brief in support of marriage equality.

The Justice Department will urge the U.S. Supreme Court to allow same-sex marriage to resume in California, wading into the protracted legal battle over Proposition 8 and giving gay-rights advocates a new court ally.

The Supreme Court will hear a case related to California’s Proposition 8 (banning “same-sex” marriage), as well as one related to the Defense of Marriage Act. LGTG and supportive organizations, businesses, politicians (including a still growing list of Republicans) and more have made major efforts, from friend-of-the-court briefs to petitions, calling for the support of marriage equality.

The NBC report recalls that earlier, the Obama administration had indicated they “would not get involved” with the issue. Then last May, Mr. Obama famously “evolved,” and expressed his personal support for marriage equality, though at the same time, he indicated it was a state, not federal, matter. The latest step, at least publicly, in the president’s evolution was in his inaugural address in January, as quoted by NBC:

“˜Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law, for if we are truly created equal, then surely the love we commit to one another must be equal as well.’
