U.S. Special Counsel Robert Mueller has subpoenaed a key assistant of long-time Donald Trump adviser Roger Stone, two people with knowledge of the matter said, the latest sign that Mueller’s investigation into alleged Russian meddling in the 2016 election is increasingly focusing on Stone.
The subpoena was recently served on John Kakanis, 30, who has worked as a driver, accountant and operative for Stone.
Kakanis has been briefly questioned by the FBI on the topics of possible Russian interference in the 2016 presidential election, the WikiLeaks website, its founder Julian Assange, and the hacker or hackers who call themselves Guccifer 2.0, one of the people with knowledge of the matter said.
Mueller has not scheduled a grand jury appearance for Kakanis, the person said.
WikiLeaks and Guccifer 2.0 each published emails and other documents from the Democratic Party in 2016 that U.S. intelligence agencies say were hacked by Russian operatives in an effort to tip the election in favor of then Republican nominee Trump.
