Former acting Secretary of Defense David Norquist has joined Washington, D.C., powerhouse Covington & Burling in its aerospace and defense industry practices. No stranger to unidentified phenomena, Norquist, who joined Covington in late May as a senior adviser, will help his clients explain the unexplainable—how government works.

The National Law Journal spoke to Norquist—who is not a lawyer—about how his government experience has prepared him to help Covington’s clients and how his expertise outside the legal profession makes him a compelling proposition to clients of a Beltway legal practice.
