MilitaryPartnerMore states are following Texas’ lead and refusing to process ID cards for same-sex spouses of National Guard troops, American Military Partner Association reports, but one state reversed course.

Indiana and South Carolina joined Texas this week in sending same-sex spouses of National Guard troops to federal facilities to register. Both states accept applications from opposite-sex spouses.

But after further legal review, Indiana reversed itself and again began taking applications at National Guard bases.

“We applaud the Indiana National Guard for doing the right thing,” said Stephen Peters, president of AMPA. “We urge other state national guards who are refusing to comply with the Defense Department directive to process all spouses for federal benefits to immediately follow suit.

Sen. Carl Levin, D-Mich., the chairman of the Senate Armed Services Committee, and Rep. Adam Smith, D-Wash., ranking member of the House Armed Service Committee, wrote to Defense Secretary Chuck Hagel asking him to intervene.

Louisiana, Oklahoma and Mississippi also began signing up all spouses but then stopped after Texas turned away applicants. In Texas, Alicia Butler was turned away from Camp Mabry on the first day same-sex spouses could sign up for IDs and is now being represented by Lambda Legal’s Dallas office.
