The move comes a day after Credico told Melber on his program that Mueller had previously requested a voluntary interview, which Credico said he declined.

"They didn’t call me in, they showed up and they asked me to come in and do an in-person voluntary interview," Credico told MSNBC on Wednesday. "They asked me if I would like to do — we set up a conversation with somebody from the Mueller team and they asked my lawyer if I would like to sit down and do a voluntary interview."

"And I said no," he said, adding that the interaction took place “five or six weeks ago."

Attorneys with Mueller's office have also sought, in recent weeks, to question Kristin Davis, a former New York City prostitution mogul and a former employee of Stone, according to news reports.

Stone has claimed that the special counsel's office has not reached out to him directly, but contend that it is "possible" he will be indicted by Mueller's office for alleged crimes.
