Special counsel Robert S. Mueller III asked the House Intelligence Committee on Friday for an official transcript of Trump adviser Roger Stone's testimony, according to people familiar with the request, a sign that prosecutors could be moving to charge him with a crime.
It is the first time Mueller has formally asked the committee to turn over material the panel has gathered in its investigation of Russian interference of the 2016 campaign, according to the people.
The move suggests that the special counsel is moving to finalize his months-long investigation of Stone — a key part of Mueller's inquiry into whether anyone in President Trump's orbit coordinated with the Russians.
Stone, who has advised Trump on and off for decades and was in contact with the candidate during the 2016 campaign, has been a focus of the special counsel as Mueller probes whether the Trump campaign had advance knowledge of WikiLeaks's release of Democratic emails allegedly hacked by Russian operatives.
Securing an official transcript from the committee would be a necessary step before pursuing an indictment that Stone allegedly lied to lawmakers, legal experts said.
The special counsel could use the threat of a false-statement charge to seek cooperation from Stone, as Mueller has done with other Trump advisers, such as former national security adviser Michael Flynn and longtime Trump lawyer Michael Cohen.
