A federal judge on Monday questioned whether a Russian company had snubbed subpoenas in a case brought by former Special Counsel Robert Mueller III’s office, saying there was a “strong likelihood” the firm failed to comply with the document demands ahead of its scheduled trial in April on charges of interference in the 2016 presidential election.

At a half-hour hearing in Washington’s federal trial court, U.S. District Judge Dabney Friedrich of the District of Columbia gave the company, Concord Management and Consulting, until Wednesday to either comply with the subpoenas or provide a detailed description of its search for the documents, along with an explanation of why it had not turned over the requested records.
