U.S. judge says Mueller case against Russian company can proceed

WASHINGTON (Reuters) - A U.S. judge on Monday refused to dismiss charges against a Russian company accused of helping fund a propaganda operation to sway the 2016 presidential election in Donald Trump's favour, saying Special Counsel Robert Mueller had not exceeded his power.

Judge Dabney Friedrich, in an opinion filed in the U.S. District court for the District of Columbia, rejected Concord Management and Consulting LLC's argument that Mueller was unlawfully appointed and lacked prosecutorial authority.
