Longtime Donald Trump adviser Roger Stone will testify in classified session before the House Intelligence Committee on July 24, his attorney said Tuesday.
Stone had asked to appear at a public hearing before the committee, which is examining the Trump campaign's ties to Russia, his attorney, Robert Buschel, told Politico.
Stone is seeking to explain last year's communications with hackers tied to Russia and WikiLeaks, which published emails stolen from Clinton campaign chairman John Podesta.
"We tried really hard," Buschel told Politico, adding that the committee said that "They're done with public."
Podesta testified Tuesday before the committee.
"I think they were trying to make the best judgments they could on behalf of the American people," Podesta said of the Obama administration's efforts to counter Moscow as he left the hearing, according to Politico.
Stone said that he specifically wanted to counter Podesta in his testimony.
"With John Podesta appearing before the committee, I do feel it is essential that I have the opportunity to rebut his serial lies," he told Politico in an email. "I may not be able to sue a member of Congress, but I sure as hell can sue the f--- out of Podesta.
"The claim that I had knowledge of the hacking of his email by WikiLeaks in advance is a demonstrable lie."
Podesta did not respond to a request for comment later, according to the report.
Buschel told Politico that Stone has been "cooperating" with House and Senate committees in their respective Moscow probes.
He said he expected a transcript of Stone's testimony to be made public.
"I'm sure Roger will be happy to tell you whatever he says," Buschel said. "I don't think there will be much mystery after that."
