As John Durham’s investigation takes shape, the question of whether the special counsel will charge anyone else at the FBI looms large.

Michael Sussmann, a Democratic cybersecurity lawyer, was indicted in September for allegedly concealing his work for the Clinton campaign when pushing claims of a connection between the 2016 Trump campaign and Russian bank Alfa Bank to the FBI’s top lawyer. And Igor Danchenko, a U.S.-based and Russian-born researcher, was charged “with five counts of making false statements to the FBI,” which Durham claims he made about the information he provided to British ex-spy Christopher Steele for his discredited dossier.
