The House Intelligence Committee obtained phone records from AT&T showing extensive communications in early April involving Nunes, Giuliani, Lev Parnas, and The Hill columnist John Solomon, according to records released in the committee’s formal reporton its investigation underlying impeachment charges against President Donald Trump.

The records shed new light on the relationship between Nunes, one of the impeachment inquiries most vehement critics, and the individuals at the center of what committee Democrats describe as an illicit campaign to weaponize U.S. foreign policy to Trump’s political advantage.

The records in the committee’s 300-page report show three phone calls between Nunes and Giuliani on April 10 of this year, and at least two with Parnas two days later. Derek Harvey, a member of Nunes’ staff, also had a phone call with Giuliani the following month.

Nunes is certain to face an ethics investigation.
