Jerome Corsi – an acquaintance of Roger Stone, a former political adviser to President Donald Trump – confirmed that the Senate Intelligence Committee has subpoenaed him for documents as well as an interview.

The subpoena calls for Corsi to appear on February 6. He said he plans to contest it. His lawyer, Larry Klayman, said they are still assessing how to respond.

The subpoena was first reported by The Hill.

A spokeswoman for the Senate Intelligence Committee declined to comment.

The committee is calling for Corsi to hand over communications, including through intermediaries, involving DCLeaks, Guccifer 2.0, WikiLeaks and any of its employees, Roger Stone, Peter Smith, Charles Johnson, the government of Ecuador, Ted Malloch, Randy Credico, Steve Bannon, Alex Jones and Henry Greenberg.

It is also seeking any communications with Trump’s presidential campaign or transition related to Russia; any attempts to search for information that may have been stolen and was related to the 2016 election; and any communications about Russia’s efforts to influence the 2016 election.

The committee is also seeking any communications related to damaging information about Hillary Clinton, such as emails about her health, the Clinton Foundation or John and Tony Podesta.

Finally, the committee wants Corsi to hand over any communications about its ongoing investigation, with the exception of communications directly with committee employees or Corsi’s attorneys. The committee also wants copies of any records Corsi provided to the special counsel or the FBI.
