The House has oversight, but corrupt trump has forbidden anyone to testify, claiming "executive privilege." Executive privilege is for certain things. The president is stonewalling legitimate oversight, and are only going to court because they are prevented by trump from getting the underlying testimony and evidence they need for evaluation. The administrative branch does not have the right to stop the legislative branch from determining what they need for oversight. The Mueller Report did not exonerate trump, and Mueller was only prevented from charging him with interference because of the special Justice rule that a sitting president cannot be indicted. A.G. Barr is a disgrace to his office, giving a prejudiced reading of the results, .... being the president's lawyer instead of the country's top lawyer. Shameful.
