Last month, Mastriano cut short a closed-door interview without answering questions from committee members. The committee refused to let Mastriano record the deposition, Mastriano’s lawsuit said, and Mastriano has concerns about how the committee might disseminate excerpts to the public from a closed-door deposition with him, the lawsuit said.
A committee spokesperson declined comment on the lawsuit, filed in federal court in Washington.
Still, Mastriano’s lawyer, Timothy Parlatore, has said his client is willing to voluntarily testify publicly before the panel and has told the FBI that he didn’t know about a planned insurrection or any coordination behind the Jan. 6, 2021, attack on the Capitol.
