Senate candidate Elizabeth Warren has called on President Barack Obama to endorse gay marriage.

The 62-year-old Warren, who is running to unseat Republican Senator Scott Brown of Massachusetts, told gay weekly The Washington Blade that marriage equality is “morally right.”

Obama has endorsed civil unions for gay and lesbian couples and has said that he's “evolving” on marriage.

“I want to see the president evolve because I believe that is right; marriage equality is morally right,” she said.

Warren said she would like to see the president sign an executive order which would require companies doing business with the government to include sexual orientation and gender identity in their non-discrimination policies.

“Any steps that the president can take toward non-discrimination benefit the whole country,” Warren said. “I don't know how else to say it. It's the right thing to do.”

Warren also endorsed adding marriage equality to the Democratic Party platform because it would help build support for repeal of the Defense of Marriage Act (DOMA), the law which bars federal agencies from recognizing the legal marriages of gay couples.
