Last week’s indictment of former Perkins Coie partner Michael Sussmann in a case tied to the 2016 presidential campaign thrust Special Counsel John Durham’s investigation into the origins of the FBI’s Russia probe back into the spotlight.

In April 2019, then-Attorney General William Barr tasked Durham, a veteran prosecutor who was then the U.S. attorney for the District of Connecticut, with investigating how the FBI began scrutinizing the Russian government’s attempts to interfere in the 2016 election and possible coordination with the Trump campaign in that effort.
