According to a bombshell document released Thursday, the primary source used for the anti-Trump Steele dossier was a Russian agent that had been the target of a previous counterintelligence investigation by the FBI.
In 2010, the FBI was considering a FISA warrant to wiretap Igor Danchenko. That is a full six years before the FBI would rely on the very information Danchenko provided to former British spy Christopher Steele in order to obtain FISA warrants against President Trump campaign adviser Carter Page. The memo shows that the FBI team investigating claims of Trump/Russian collusion were aware in December of 2016 that Danchenko had been investigated six years prior.
"This is the most stunning and damning revelation the committee has uncovered," Senate Judiciary Committee Chairman Lindsey Graham said.
Graham and other Republicans see this as further evidence that Russian meddling in the 2016 election came, at least in one significant way, with the disinformation that was given to Steele as he worked with the Hillary Clinton campaign and DNC to investigate the Team Trump.
