Attorney General Eric Holder announced Thursday that the Obama administration had filed a legal brief encouraging the Supreme Court to overturn California’s ban on same-sex marriage. Holder said in a statement:

In our filing today in Hollingsworth v. Perry, the government seeks to vindicate the defining constitutional ideal of equal treatment under the law. Throughout history, we have seen the unjust consequences of decisions and policies rooted in discrimination. The issues before the Supreme Court in this case and the Defense of Marriage Act case are not just important to the tens of thousands Americans who are being denied equal benefits and rights under our laws, but to our nation as a whole.

Holder hinted yesterday that the administration might insert itself into the case, telling ABC News that “this is really the latest civil-rights issue.” In short, the brief argues that tradition cannot justify discrimination against a minority group.

The filing of the brief was big news to supporters of same-sex marriage, who sent #Prop8 trending.

Not everyone is so happy to see Obama and his administration evolve.
