ROGER STONE — It was nearly two weeks ago when Republican operative Roger Stone, a longtime adviser to Donald Trump, said he'd invoke his Fifth Amendment rights instead of cooperating with the committee investigating the Jan. 6 attack. But in practical terms, he still had to show up and plead the Fifth while sitting down with investigators.

Today, as NBC News reported, that's exactly what happened.

The House committee investigating the Jan. 6 riot at the Capitol on Friday questioned Roger Stone under oath about the attack, but the longtime adviser to former President Donald Trump said he didn't give them any answers.

Stone told reporters he was concerned about Democrats "fabricating perjury charges on the basis of comments that are innocuous, material or irrelevant." He's also claimed not to have been involved with the violent pro-Trump riots.

Circling back to our earlier coverage, there is a certain symmetry to the circumstances. In December 2018, after two members of Trump's inner circle had already pleaded the Fifth, Republican operative Stone told congressional investigators that he, too, was invoking the Fifth Amendment's protection against self-incrimination as lawmakers investigated the Russia scandal.

In December 2021, after two Republican lawyers close to the former president — Jeffrey Clark and John Eastman — pleaded the Fifth as part of the investigation into the Jan. 6 attack, Stone is once again doing the same thing.

The decision means there are now three people in the former president's inner circle who have said they'll refuse to answer questions about the Jan. 6 attack for fear that their answers may be used against them in possible criminal proceedings.
