Virginia Attorney General Ken Cuccinelli announced on Friday that his office would no longer use the law firm King & Spalding due to the firm's decision to withdraw from representing House Republicans in ongoing litigation challenging the constitutionality of the Defense of Marriage Act (DOMA), which federally bans gay marriage, The Washington Examiner reported.

The Atlanta-based firm on Monday announced it would drop the case, prompting partner Paul Clement to jump ship to the Washington-based Bancroft PLLC, where he'll continue to work on the case. House leaders took on the task of defending the law after President Barack Obama announced he would no longer because he believes the law is unconstitutional.

In a letter to King & Spalding, Cuccinelli, a Republican, wrote that the firm's decision “was such an obsequious act of weakness that I feel compelled to end your legal association with Virginia so that there is no chance that one of my legal clients will be put in the embarrassing and difficult situation like the client you walked away from, the House of Representatives.”

“Virginia seeks firms of commitment, courage, strength and toughness, and unfortunately, what the world has learned of King & Spalding, is that your firm utterly lacks such qualities.”

Cuccinelli said he was terminating the state's relationship with King & Spalding “effective immediately.” The firm was first placed on retainer by Cuccinelli's predecessor, Republican Bill Mims, in 2009.

Cuccinelli made headlines in March when just weeks after taking office he called on the state's colleges and universities to rescind anti-discrimination policies based on sexual orientation, calling such protections illegal. He's also opposed giving gay couples the right to adopt.
