Yes, they recalled a grand jury just for this - and no charges have been announced.
Insider experts, like the former spokesman for DoJ, are speculating there's a good chance their case is so bad, even the grand jury is refusing to indict, which almost never happens. This is about trump abusing his power to persecute, not about 'the establishment' having privilege. While they DO have privilege, this is selective prosecution. Two prosecutors have left the team, complaining about it.
If you want to actually read about the privilege of the elite people, and McCabe is outranked by a president which is why the DoJ officials are trying to prosecute him at trump's demand (after they fired him 26 hours before he could get retirement benefits for 20 years of service), Glenn Greenwald's "With Liberty and Justice for Some" is about exactly that topic.
It discusses how our laws and courts and jails are mostly for 'the little people' and how the wealthy and powerful largely have immunity. Which is partly what makes the attempted prosecution of McCabe here all the more an aberration and selective prosecution for political use of the law. What did he do wrong, again? You do realize he's a Republican, like Comey?
You need to get a clue what this is about: trump is a criminal and so he attacks the threats to telling the truth about him - the news media, and the investigative authorities like the FBI. It sounds crazy to let a crook demonize the FBI to get away with crime, but that's just what trump is trying to do and you are helping.
That's why Republicans are looking for any attacks, and attacked McCabe wrongly; he had an internal talk defending the investigation of the *Clintons*, and when he was attacked by these phony trump-driven accusations, he allowed a reported to tell the WSJ about that conversation, which was his right to do. This is all about protecting trump's crimes by persecuting the FBI.
