The Washington-based Russian national who supplied former British intelligence officer Christopher Steele with most of the unverified claims in the infamous Russia dossier was himself investigated by the FBI on suspicions of being a spy for the Kremlin, according to documents released by Attorney General William Barr.
Though he isn’t identified by name in the documents released on Sept. 24, Igor Danchenko was identified in July as the primary source for the Steele dossier. The FBI investigated Danchenko from 2009 to 2011 because he “may be a threat to national security,” according to an unclassified summary (pdf) of the probe provided to Sen. Lindsey Graham (R-S.C.) by Barr.
