The Russia probe that has dogged the Trump administration isn’t going away any time soon. The Wall Street Journal writes:

Special Counsel Robert Mueller has impaneled a grand jury in Washington to investigate Russia’s interference in the 2016 elections, a sign that his inquiry is growing in intensity and entering a new phase, according to two people familiar with the matter.

The grand jury, which began its work in recent weeks, is a sign that Mr. Mueller’s inquiry is ramping up and that it will likely continue for months. Mr. Mueller is investigating Russia’s efforts to influence the 2016 election and whether President Donald Trump’s campaign or associates colluded with the Kremlin as part of that effort. [...]

Before Mr. Mueller was tapped in May to be special counsel, federal prosecutors had been using at least one other grand jury, located in Alexandria, Va., to assist in their criminal investigation of Michael Flynn, a former national security adviser. That probe, which has been taken over by Mr. Mueller’s team, focuses on Mr. Flynn’s work in the private sector on behalf of foreign interests.

Impaneling a grand jury empowers prosecutors with more investigative tools like subpoenaing documents, questioning witnesses under oath, and seeking indictments. The move indicates that Mueller is homing in on areas where he will need those legal tools at his disposal to dig deeper and build a case. 

“This is yet a further sign that there is a long-term, large-scale series of prosecutions being contemplated and being pursued by the special counsel,” said Stephen I. Vladeck, a law professor at the University of Texas. “If there was already a grand jury in Alexandria looking at Flynn, there would be no need to reinvent the wheel for the same guy. This suggests that the investigation is bigger and wider than Flynn, perhaps substantially so.”
