Effectively the four page letter from president Trump’s White House lawyer Emmet Flood to the Department of Justice is the rebuttal to the Mueller report, that it should not have included any of the evidence because no charges were brought for “collusion,” that Mueller violated the law in so doing, also in violation Mueller’s having declined to decide whether or not to charge on obstruction in order that the evidence would be made known (illegally) for the Democrats in Congress to use against Trump.
