In response to B.R. Proof of obstruction is what the investigation is supposed to find out. If the president is innocent, he has nothing to fear. However there is overwhelming evidence that the president may have tried to obstruct justice by asking numerous intelligence officials to make the Russia investigation go away. I wonder if you were as concerned about the millions of dollars congress spent doing more than 5 separate investigations into Benghazi and none of them ever had a shred of evidence that a scandal existed much less were able to prove any wrongdoing. The real reason Benghazi happened was because Republicans, hating Hilary Clinton, refused to fund the State Department with the money requested for embassy Security.
