The House Intelligence Committee has decided to postpone testimony from informal Trump adviser Roger Stone as part of its investigation into Russian meddling in the 2016 election, according to a report.
Stone's lawyer, Grant Smith, told Bloomberg that Stone's appearance before the committee has been delayed until after Congress returns from the August recess.
Stone was initially scheduled to testify in a closed-door session July 24, but Smith said the House Intelligence Committee wasn't ready yet.
Smith said in the interview that Stone is upset his testimony has been postponed because he has "been taking it on the chin" with false statements made against him.
Trump's longtime confidante had asked to testify in an open session to discuss his communications with Russian-linked hackers and WikiLeaks, which published a trove of hacked emails from Hillary Clinton campaign chair John Podesta and the Democratic National Committee.
Podesta met with the House Intelligence Committee last month, and Stone said then he wanted to testify to refute Podesta's claims.
The committee's decision to postpone Stone's testimony comes after he insulted two Democratic committee members while appearing on a radio show in Buffalo, N.Y.
Stone was interviewed by Michael Caputo, a communications adviser to the Trump campaign who is testifying before the House Intelligence Committee on Friday.
During the interview, Stone threatened to sue Rep. Jackie Speier, D-Calif., who said Stone was being paid by the Kremlin.
"Ok, congresswoman. You have two choices — apologize or I'll see you in U.S. District Court in California," Stone said. "You see, members of Congress can be sued when they say things outside the floor. She said that on television, and therefore, I will be suing her."
Stone also criticized Rep. Eric Swalwell, D-Calif., who also sits on the House Intelligence Committee.
"Have you seen this guy, Eric Swalwell? The lightweight, mannequin, pretty boy from California? I think he's a yellow-bellied coward, and I don't think he will show," Stone said. "But if he does show, he will regret it for the rest of his life."
