In November 2021, Durham also charged Russian national Igor Danchenko of making false statements. Danchenko, who pleaded not guilty, is accused of lying about the source of information that he provided to Christopher Steele for his "dossier" on Trump.

In 2020, Durham charged former FBI lawyer Kevin Clinesmith with making a false statement – the first criminal case arising from his probe. Clinesmith was referred for potential prosecution by the Justice Department's inspector general's office, which conducted its own review of the Russia investigation.

Specifically, the inspector general accused Clinesmith, though not by name, of altering an email about Page to say that he was "not a source" for another government agency. Page has said he was a source for the CIA. The DOJ relied on that assertion as it submitted a third and final renewal application in 2017 to eavesdrop on Trump campaign aide Carter Page under the Foreign Intelligence Surveillance Act (FISA). 

Former Attorney General Bill Barr appointed Durham, then the U.S. attorney from Connecticut, in 2019 to investigate the origins of the FBI’s original Russia probe, or Crossfire Hurricane, which began in July 2016, through the appointment of Special Counsel Robert Mueller in May 2017 shortly after Mueller completed his years long investigation into whether Trump's campaign colluded or coordinated with the Russians to influence the 2016 presidential election.

Mueller's investigation found no evidence of illegal or criminal coordination between Trump or the Trump campaign and Russia in 2016.  

Barr, in December 2020, before leaving the Trump administration, tapped Durham as special counsel to continue his investigation through the Biden administration.

In the scope order, Barr stated that Durham "is authorized to investigate whether any federal official, employee, or any other person or entity violated the law in connection with the intelligence, counter-intelligence, or law-enforcement activities directed at the 2016 presidential campaigns, individuals associated with those campaigns, and individuals associated with the administration of President Donald J. Trump, including but not limited to Crossfire Hurricane and the investigation of Special Counsel Robert S. Mueller, III."

Under U.S. code, the special counsel would produce a "confidential report" and is ordered to "submit to the Attorney General a final report, and such interim reports as he deems appropriate in a form that will permit public dissemination."
