Washington (CNN)The White House is working behind the scenes to limit the testimony to congressional investigations into Russian meddling in the 2016 election, according to multiple sources.
The attempts to curtail testimony to congressional investigators became clear this week when former White House chief strategist Steve Bannon appeared before the House Intelligence Committee and infuriated both sides of the aisle by refusing to answer questions about his work during the presidential transition and in the White House.
At some points during Bannon's six hours of closed-door testimony, his attorney took breaks to confer via telephone with the White House counsel's office to clarify what questions could be answered and came back with the same guidance: Bannon could not discuss any activities related to the transition or his tenure in the White House.

So the House can impeach, they just aren't allowed to know any information in order to impeach because Twitler says so. Congress critters with the highest level of national security clearance are not allowed to hear answers because of "Executive Privilege." This "Executive Privilege" even back-applies to before Twitler was President because the mentally healthy Orange Menace says so.
This was not a case of executive privilege. It was worse than that. The argument was that Bannon could answer no questions so that the White House could at some later date, at its option, try to exert some kind of privilege. The questions being asked were about many things that would not normally be covered by executive privilege, e.g. conversations he had with people other than the President.
There is a bit of Kabuki theater going on here, because Mueller apparently did not want Bannon to answer any questions. Had he done so, that testimony would have been conveyed straight to the White House by Congressional allies and tipped them off as to what kind of defense they needed to mount against the Mueller investigation, when Mueller eventually got around to questioning Bannon. Bannon seems to now have an agreement with Mueller to cooperate fully with his investigation. If true, that is very bad news for Trump. Meanwhile, Bannon will not be called back in the near future to answer questions that he really was obligated to answer in the first place. Short of asserting his 5th amendment rights, he had no privilege to ignore the congressional subpoena.
