Preston himself is a hybrid of Langley and the Pentagon. In the Clinton administration he served as acting general counsel at DOD and was principal deputy general counsel from 1993 to 1995. Previously, he was general counsel of the Navy. Preston later was deputy assistant attorney general under Clinton.
Prior to joining CIA, Preston was a partner at the power firm of Wilmer Cutler Pickering Hale and Dorr, where he worked on defense contracts.
In April, Preston gave a speech at Harvard Law School, where he earned his law degree in 1983, on CIA and the rule of law, arguing that intelligence operations permeate most national security crises.
“It may be that intelligence has never been more important than it is today. At the very least, the intel business is booming,” he said.
Preston’s speech was a list of assurances that everything the agency does strictly adheres to U.S. law, as well as other internal and external checks.
“Just as ours is a nation of laws, the CIA is an institution of laws and the rule of law is integral to Agency operations.”
Preston, a Yale graduate, also gave an interview to Yale Undergraduate Law Review, in which he said he was struck by the greater coordination between intelligence and military operations when he joined CIA in 2009 than when he previously served at DOD in the 1990s.
Asked where he may end up after CIA, Preston said, “Actually, someone in my position would typically be gone by the end of the first term. As for where I will go … I do not know exactly, and that does not bother me.”
