Washington Rep. Adam Smith, a Democrat, on Thursday reintroduced a bill which seeks to provide equal benefits to gay service members.

The Military Spouses Equal Treatment Act of 2013 (MSET) would change the definition of “spouse” in four key areas of U.S. code related to recognition, support and benefits for married service members and veterans.

Allyson Robinson, executive director of OutServe-SLDN, thanked Smith, a ranking member of the House Armed Services Committee, for reintroducing the measure.

“Since the repeal of 'Don't Ask, Don't Tell' there have been two classes of service members in this country – one that receives the nation's full recognition, support and benefits and one that does not,” Robinson said in a statement. “By making an arbitrary distinction between gay and lesbian troops and their straight comrades, and forcing commanders to play favorites, the law as it stands harms all service members and weakens the force. This legislation fixes that problem.”

OutServe-SLDN said that the legislation was needed even if the Defense of Marriage Act (DOMA) were to be struck down or repealed because “they address entirely separate laws governing support and benefits for military members and veterans.”

On Tuesday, President Barack Obama called for equal benefits for gay troops in his State of the Union address. However, the president did not endorse any specific remedy.
