What's a little nullification among friends?

From a speech by Defense Secretary Chuck Hagel (emphasis added):

When the Supreme Court issued its decision on the Defense of Marriage Act this summer, the Department of Defense immediately began working on providing the same benefits to all eligible spouses, regardless of sexual orientation. We did it because everyone who serves our country in uniform should receive the full benefits they earned, fairly and in accordance with the law. Everyone’s rights must be protected.  

This means that all spouses of service members are entitled to DoD ID cards, and the benefits that come with them. But several states are refusing to issue these IDs to same-sex spouses at National Guard facilities. Not only does this violate the states’ obligations under federal law, their actions have created hardship and inequality by forcing couples to travel long distances to federal military bases to obtain the ID cards they’re entitled to.  

This is wrong. It causes division among the ranks, and it furthers prejudice, which DoD has fought to extinguish.  

Today, I directed the Chief of the National Guard Bureau, General Frank Grass, to take immediate action to remedy this situation. At my direction, he will meet with the Adjutants General from the states where these ID cards are being denied. The Adjutants General will be expected to comply with both lawful direction and DoD policy, in line with the practices of 45 other states and jurisdictions. 

From The State (emphasis added):

In his remarks prepared for an Anti-Defamation League centennial dinner speech, Hagel did not name the states that are defying Pentagon policy on this issue. But the Pentagon has cited nine: Florida, Georgia, Indiana, Louisiana, Mississippi, Oklahoma, South Carolina, Texas and West Virginia. 

The Pentagon says there are 114 Army and Air National Guard sites in those nine states that are not providing ID cards to eligible same-sex spouses.
