The White House has released a trove of declassified documents showing that the FBI opened a secret 2017 counterintelligence investigation into whether President Donald Trump was acting on behalf of Russia when he fired FBI Director James Comey.
The investigation, codenamed “Oxferd Comma,” was launched in May 2017 immediately following Comey’s dismissal, according to documents published through the White House’s Government Transparency Task Force.
An FBI memo dated May 16, 2017 stated that investigators sought to determine whether Trump was “directed by, controlled by, and/or coordinated activities with, the Russian Federation in a manner constituting a threat to the national security of the United States and/or a violation of federal criminal statutes.”
The opening memo also indicated that investigators would examine whether Trump or others had obstructed, or conspired to obstruct, an associated FBI counterintelligence investigation already underway.
The probe drew heavily on information developed during Crossfire Hurricane, the FBI’s earlier counterintelligence investigation into potential coordination between Trump’s 2016 presidential campaign and the Russian government.
Additional factors cited in the memo included Trump’s interactions with Comey, the administration’s shifting explanations for the firing, Trump campaign discussions about Republican platform language on Ukraine aid, and Trump’s business ties and real estate interests involving Russia.
Trump initially pointed to Comey’s handling of the Hillary Clinton private email server investigation as justification for the firing, though he later acknowledged the Russia investigation had also factored into his thinking.
The FBI memo noted that the circumstances surrounding Comey’s dismissal could support an inference that the bureau’s counterintelligence investigation was a factor in Trump’s decision, though the opening of a probe did not mean those suspicions had been substantiated.
Special counsel Robert Mueller, appointed in 2017, reported in 2019 that his team did not establish coordination between the Trump campaign and Russia and did not reach a prosecutorial decision on obstruction of justice.
Attorney General William Barr appointed John Durham to review the origins of the Russia investigation in 2019, and Durham’s 2023 report concluded that the FBI opened the Crossfire Hurricane investigation without sufficient evidentiary support.
A separate 2019 Justice Department inspector general review found the FBI had sufficient grounds under its own rules to open Crossfire Hurricane, though it later identified serious errors in surveillance applications involving former Trump campaign adviser Carter Page.
The unusual spelling of the codename drew attention from former acting Assistant Attorney General Jeff Clark, who said a document expert he consulted concluded the “o” in “Comma” was actually a zero, speculating it may have been designed to obstruct FOIA searches.
The documents were declassified and released on Wednesday through the White House’s Government Transparency Task Force, representing one of the most significant disclosures related to the origins of the federal government’s Russia inquiry.
