Concord Management and Consulting, LLC. - one of three businesses indicted by Mueller in February along with 13 individuals for election meddling, surprised the special counsel in April when they actually showed up in court to fight the charges. Mueller's team tried to delay Concord from entering the case, arguing that thee Russian company not been properly served, however Judge Dabney Friedrich denied the request - effectively telling prosecutors 'well, they're here.' 

Concord was accused in the indictment of supporting the Internet Research Agency (IRA), a Russian 'troll farm' accused of trying to influence the 2016 US election. 

On Thursday, Judge Freidrich asked Mueller's prosecutors if she should assume they aren't accusing Concord of violating US laws applicable to election expenditures and failure to register as a foreign agent. 

Concord has asked Dabney to throw out the charges - claiming that Mueller's office fabricated a crime, and that there is no law against interfering in elections.
