5/11/18 New bipartisan attempt to protect Mueller's investigation by preserving and reporting fruits of investigation if fired. https://www.nbcnews.com/politics/congress/lawmakers-weigh-plan-b-protect-mueller-s-work-n873241
A version of this was published in the Sky Hi News May 7, 2018.
DOJ refuses to release information Nunes demanded because it asked for disclosure of the redacted information on what the DOJ says is an intelligence source and to release that name would damage national security and imperil the life of the source. The DOJ and Democrats on the the House Intelligence committee which Nunes chairs believes that 1) Donald Trump is looking for a pretext to fire Rosenstein if he does not provide the information and that 2) the information would flow to the White House, giving them inside information, a roadmap, needed for a defense against Mueller findings. Also imperiled in this is Attorney Jeff Sessions as well as Rod Rosenstein, since their refusal to turn over the classified information of ongoing investigations...long policy of the DOJ... This could open up the pretext for the President to fire Sessions and Rosenstein or for the impeachment of Rosenstein and then to close down the Mueller probe. As of 5/10/18, the issue is kicked over until next week. (comments per Ari Melber and guests on MSNBC). Impeachment of Rosenstein would take that off the hands of the President who probably would trigger impeachment for obstruction of justice action if he did it. This way one cannot impeach Nunes and his GOP cohorts who also received backing from Speaker Ryan to day for wanting to expose a secret source..
If Donald Trump cannot fire Rod Rosenstein because it would look too much like obstruction of justice, then the House Freedom Caucus is trying to impeach Rod Rosenstein, Deputy Attorney General, who oversees the Mueller Russian investigation. Their impeachment attempt begins this week. The House Freedom Caucus is clearly trying obstruct justice by crippling the Mueller investigation to oust his boss, Rosenstein, in hopes that a Trump loyalist would take his place and rein in the Mueller investigation. Clever. There is no way to impeach the House members for their obstructing justice.
In the meantime, a handful of Senators made it clear they would not approve attempts to oust Mueller, enough given the closely divided Senate to stop amy impeachment attempts of Rosenstein. Bills have been introduced to protect Mueller, but have gotten nowhere because the Senate GOP leader refuses to bring the bills up to a vote, claiming it was unnecessary since the White House had no plans to fire Mueller. Whether those same senators would oppose impeaching Rosenstein is not known, but given the close partisan balance in the Senate, getting a 2/3 vote to convict and oust would still be an impossibility.
