Ex-FBI Director Comey adviser subpoenaed by federal prosecutors in criminal probe: report

An adviser of former FBI Director James Comey was subpoenaed by federal prosecutors in connection with a criminal probe, according to a report.

The adviser, Columbia law professor Daniel Richman, was subpoenaed last week, sources told ABC News, according to a news report Wednesday.

Richman has previously said he was an intermediary between Comey and reporters following Comey's 2017 firing by President Trump after the FBI's investigation into his 2016 presidential campaign. The professor reportedly met with federal prosecutors in the Eastern District of Virginia on Tuesday.

The subpoena is part of an investigation into Comey's congressional testimony in September 2020 about the Russia collusion investigation, per ABC News' sources.

Richman has said publicly that he shared with a New York Times reporter the content of Comey's memos about his interactions with Trump.

Trump said that Comey broke the law by sharing the memos, arguing that they had classified information. Richman told ABC News that none of the documents had any classification markings.

He insisted to federal agents that he did not believe he had confirmed or provided classified intelligence to reporters but said he could not be 100% certain, noting he could only make his leak denial “with a discount.”

While Comey has defended his handling of the Russia collusion investigation's early stages, a prior investigation by the Justice Department's inspector general found that he violated FBI policies with his handling of the memos.

The DOJ and attorneys for Richman and Comey didn't respond to ABC News' requests for comment.
