Robert Mueller reveals he has grand juries going against Jared Kushner and/or Donald Trump Jr

Special Counsel Robert Mueller threw a curveball into the Trump-Russia saga today when he subpoenaed Steve Bannon to testify before a grand jury in Donald Trumpโs Russia scandal. This is notable because itโs the first known instance of Mueller hauling one of Trumpโs seniormost advisers before a grand jury. Itโs even more notable because people are not subpoenaed to testify in a grand jury against themselves. This means Mueller has grand juries underway against other people in the Trump-Russia scandal. Based on the progress thatโs already been made in terms of climbing up the ladder of Trumpโs advisers, this grand jury can only be against a handful of people.
The New York Times was the first to report the subpoena this morning, and itโs reporting revealed that Bannon is being called to testify about the actions of Trumpโs other advisers in relation to Russia. But at this point, whoโs left? Weโre long past the point of the investigation being focused on middling figures like George Papadopoulos. The case against Paul Manafort has already moved beyond grand jury to impending trial. Michael Flynn has already cut a deal.
Realistically speaking, the remaining grand jury targets are Jared Kushner and Donald Trump Jr. Considering that Bannon made criminal assertions against them both in the Fire and Fury book, it makes perfect sense that Mueller would bring Bannon in to testify against either or both of them.
As Palmer Report pointed out earlier, Robert Muellerโs decision to subpoena Steve Bannon for a grand jury means that Bannon isnโt a target, which in turn means Bannon has probably already agreed to a deal. The subpoena may simply be Bannonโs way of having legal cover against any lawsuits Donald Trump might try to bring against him (link). In the meantime, Mueller just revealed that he has grand juries going against Kushner and/or Trump Jr, which means the stakes are higher than ever.
