Igor Danchenko, a Russian analyst who was a source for the 2016 dossier of allegations about former President Donald Trump, was arrested and indicted Thursday for allegedly lying to the FBI, as part of Special Counsel John Durham’s investigation into the origins of the FBI’s Russia investigation.

He was charged with five counts of making false statements to the FBI, according to the indictment that was unsealed Thursday, and faces up to five years in prison for each count.

Danchenko was a key source of information used by former British intelligence operative Christopher Steele in a dossier that alleged Trump was compromised by ties to Russia ahead of the 2016 election. The dossier, which many of the claims in it were never proven, became one of the most controversial parts of the FBI’s 2016 investigation into Trump and Russia, known as “Crossfire Hurricane,” which led to special counsel Robert Mueller’s investigation.

Among the salacious claims Danchenko has said he passed on was that the Russians had a tape of Trump with women that became infamously shorthanded as the pee tape. Trump has denied such an episode ever occurred.

In a move that the Justice Department inspector general later found issues with, the FBI used Steele’s dossier to obtain a foreign surveillance warrant on former Trump campaign aide Carter Page.

The indictment unsealed Thursday specifically faults Danchenko for contributing information that became part of the FBI’s foreign intelligence surveillance warrants on Page.

The Trump dossier produced by Steele “as well as information collected for the reports by Danchenko, played a role in the FBI’s investigative decisions and in sworn representations that the FBI made to the Foreign Intelligence Surveillance Court throughout the relevant time period,” the indictment says.

The indictment also fleshes out alleged lies related to two of Danchenko’s supposed interactions.

In one instance, prosecutors accuse Danchenko in FBI interviews of hiding that a US-based PR executive with ties to Democratic politics was a source of his and helped him network for Steele’s work.

“PR Executive-l maintained historical and ongoing involvement in Democratic politics, which bore upon PR Executive-l’s reliability, motivations, and potential bias as a source of information,” the indictment states.

In another, prosecutors suggest Danchenko made up an anonymous phone call he said he believed came from a Russian-American chamber of commerce leader.

The call with the chamber of commerce president was a reason th
