AP: Mueller using grand jury in D.C. Russia investigation

WASHINGTON—Special Counsel Robert Mueller is using a grand jury in Washington as part of an investigation into potential coordination between the Trump campaign and Russia, a person familiar with the probe said Thursday.

The use of a grand jury, a standard prosecution tool in criminal investigations, suggests that Mueller and his team of investigators are likely to hear from witnesses and demand documents in the coming weeks and months. The person who confirmed to The Associated Press that Mueller had turned to a grand jury was not authorized to discuss the investigation by name and spoke on condition of anonymity.

The Wall Street Journal first reported the use of a grand jury.

Grand juries are common vehicles to subpoena witnesses and records and to present evidence, though they do not suggest any criminal charges are near or will necessarily be sought. It was not immediately clear how or whether the Washington grand jury was connected to the work of a separate one in Alexandria, Virginia. That panel has been used to gather information on Michael Flynn, Trump’s former national security adviser.

A spokesman for Mueller’s team did not return an email seeking comment.

Mueller’s reliance on a grand jury is the “logical next step in this investigation” given that it’s the traditional method for prosecutors to gather evidence, said Washington defense lawyer Jacob Frenkel.

“The use of the grand jury neither escalates, nor establishes a timeline for, the investigation,” he added.
