King & Spalding has brought on Joel McElvain, a former senior U.S. Department of Justice official who resigned last year following the Trump administration’s decision not to defend a portion of the Affordable Care Act, also known as Obamacare.

McElvain spent more than 20 years at DOJ, most recently as assistant branch director with the federal programs branch. King & Spalding’s “strong global platform, collaborative culture, and entrepreneurial spirit” attracted him to the firm, he said in a Jan. 16 release announcing his addition as a partner in the Washington, D.C. office.
