Roger Stone

Roger Stone, a longtime adviser of President Trump, complained of partisan behavior by special counsel Robert Mueller's investigation on Sunday, but also speculated that he could be under investigation by Mueller for a crime unrelated to coordinating with Russia leading up to the 2016 presidential election.

"It is not inconceivable now that Mr. Mueller and his team may seek to conjure up some extraneous crime, pertaining to my business, or maybe not even pertaining to the 2016 election," Stone said, in an appearance on NBC's Meet The Press.

A former campaign aide to Donald Trump appears to have changed his mind and will not fight a subpoena he says he has received in the Russia investigation — after daring special counsel Robert Mueller to arrest him in multiple media appearances.

Sam Nunberg called reporters and TV news programs on Monday and said live that he'd gotten a grand jury subpoena as part of Mueller's investigation asking for communications with other people in the Trump orbit — but that he would not comply.
