Jan. 6 Panel Explores Links Between Trump Allies and Extremist Groups

In their relationships with President Donald J. Trump in recent years, Roger J. Stone Jr., his longtime political adviser, and Michael T. Flynn, who was briefly his national security adviser, have followed a similar trajectory.

Both were either convicted of or pleaded guilty to charges stemming from the investigation into the Trump campaign’s connections to Russia. Both were pardoned by Mr. Trump after the 2020 presidential election. And both supported Mr. Trump in his relentless, multilayered efforts to reverse its outcome and remain in power.

The two were, in a sense, together again on Tuesday, when both were mentioned within an instant of one another at the House select committee hearing by Cassidy Hutchinson, an aide to Mark Meadows, Mr. Trump’s final chief of staff. Ms. Hutchinson told the panel that on Jan. 5, 2021, a day before the Capitol was stormed, Mr. Trump had directed Mr. Meadows to reach out to Mr. Stone and Mr. Flynn.

Ms. Hutchinson acknowledged that she did not know what her boss may have said to the men. But her testimony was the first time it was revealed that Mr. Trump, on the eve of the Capitol attack, had opened a channel of communication with a pair of allies who had not only worked on his behalf for weeks challenging the results of the election, but who also had extensive ties to extremist groups like the Proud Boys and the Oath Keepers, who were soon to be at the forefront of the violence.

The question of whether there was communication or coordination between the far-right groups that helped storm the Capitol and Mr. Trump and his aides and allies is among the most important facing the Jan. 6 investigators.

Barring a criminal prosecution — or something else that could force the details of the calls into the public sphere — it could be tough to be figure out exactly what Mr. Meadows discussed with Mr. Stone and Mr. Flynn.

Since late last year, Mr. Meadows has refused to comply with a committee subpoena that seeks his testimony about the weeks leading up to Jan. 6 — a move that risked his indictment on contempt of Congress charges. As for Mr. Stone and Mr. Flynn, both repeatedly exercised their Fifth Amendment rights against self-incrimination during their own interviews with the committee.

Mr. Flynn’s interview was especially remarkable, according to a recording of it played at the hearing on Tuesday. A former three-star general who still collects a military pension, Mr. Flynn pleaded the Fifth Amendment even when he was asked if he believed the violence at the Capitol was wrong, and whether he supported the lawful transfer of presidential power.

Ms. Hutchinson also told the panel that she recalled hearing about the Proud Boys and the Oath Keepers while the planning was taking place for Mr. Trump’s public event near the White House on Jan. 6 — a time, she explained, when the former president’s lawyer, Rudolph W. Giuliani, had been around.

It is possible that Mr. Stone and Mr. Flynn will receive more attention when the panel reconvenes for its next public hearing in July. That is when Representative Jamie Raskin, Democrat of Maryland, has said he intends to lead a presentation that will focus on the roles…
