I’m guessing that the impeachment articles have nothing to do with Mueller or the raid on Michael Cohen. They’re probably related to Rosenstein’s stalling after Devin Nunes demanded to see the document that launched the Russia probe. Rosenstein held off on that for so long that Nunes threatened on national television a few days ago to have him impeached if he didn’t comply. But Rosenstein did ultimately comply. Trey Gowdy was invited to the DOJ to view the document Nunes had requested on behalf of House Republicans on the Intel Committee. “Although the subpoenas issued by this Committee in August 2017 remain in effect, I’d like to thank Deputy Attorney General Rosenstein for his cooperation today,” said Nunes afterward. It may be, then, that articles of impeachment were drafted a week or two ago and are still sitting around but unlikely to be introduced now that the standoff between Nunes and Rosenstein has been resolved.
