2016 ELECTION/LEGAL/ROBERT MUELLER/RUSSIA/TRUMP PEOPLE/SAM NUNBERG: “Former Trump campaign aide Sam Nunberg, who threatened earlier this week to defy a subpoena from special counsel Robert Mueller, showed up Friday [3-9-18] morning at the federal courthouse in Washington, where he appeared set to answer prosecutors’ questions in the ongoing probe of alleged collusion between Trump aides and Russia.
Nunberg faced a throng of cameras as he arrived just after 9 a.m. along with his attorney, Patrick Brackley… Mueller’s prosecutors were not seen in the courthouse Friday morning, but they, too, have taken to entering through an underground garage.
Nunberg’s arrival at the courthouse capped a whirlwind week that started with his anonymous leaking to the media of a Mueller subpoena for his communications with Trump and other members of the president’s inner circle… Despite Nunberg’s initial talk of ignoring the subpoena and potentially risking arrest for contempt of court, he soon backed down and agreed to comply. But the story took yet another twist Tuesday, when Fox Business Network reporter Charles Gasparino said he’d spoken with Nunberg, who reportedly said he was planning to enter substance abuse treatment after his grand jury testimony Friday…
The former Trump aide’s public flirtation with skipping the grand jury appearance, the lawyer added, may have been a strong indication to Mueller that he was still worth talking to.”
