'Knock it off': Judge delivers scathing rebuke of 'unprofessional' lawyer for Mueller-indicted Russian firm

The attorneys representing Concord Management and Consulting, the Russian firm indicted by special counsel Robert Mueller for conspiracy to defraud the United States during the 2016 election, got a brutal smackdown from a Trump-appointed judge on Monday.

As reported by BuzzFeed News' Zoe Tillman, Judge Dabney Friedrich gave Concord attorney Eric Dubelier a dressing down in court by slamming his strategy as "unprofessional, inappropriate, and ineffective."

In particular, the judge faulted Dubelier for making a reference to the movie "Animal House" in his motion to dismiss charges against his client, which she said was "undermining your credibility in this courthouse."

The judge then told Dubelier to "knock it off."

According to Tillman, Dubelier replied by accusing the judge of unacceptable bias by thrashing his legal strategy.

"Dubelier pushed back, saying the judge had personally attacked him, and Friedrich replied by saying he had made personal attacks on Mueller's office," writes Tillman. "Dubelier said he was just telling the truth."

Last year, Friedrich similarly shut down Concord's effort to get Mueller's probe declared unlawful by asserting that the indictment of the firm was well within Mueller's mandate as the special counsel investigating Russian election interference.
