ALEXANDRIA, Va.—FBI agents investigating the anti-Donald Trump dossier authored by former British intelligence officer Christopher Steele should have done a better job investigating the truthfulness of its source, special counsel John Durham said in closing arguments for the source’s trial on Oct. 17.
Durham said FBI agents should have performed a “detailed review” of Igor Danchenko, the source, and his statements, including a behavioral assessment, an examination of Danchenko’s finances, and a polygraph test, at least some of which were recommended by FBI experts.
