A federal judge on Monday pressed lawyers to prepare for an April trial in the prosecution of a Russian company charged with interfering in the 2016 presidential election, expressing frustration over delays in a case that was originally brought by former Special Counsel Robert Mueller III’s office.

“We’re now on a trial track,” declared U.S. District Judge Dabney Friedrich of the District of Columbia, during a 90-minute court hearing in Washington’s federal trial court. She added: “If I left this up to you all, we wouldn’t be trying this case until 2021.”
