Blowing smoke up their collective butts or is a swamp creature. Wray knows that the president can legally and Constitutionally direct him to do investigations and activities. He's not as 'independant' as he tells Linda Graham and the other pompous senators who always want to seperate presidential appointees from Repub presidents, which goes doubly for Trump with these clowns.
Plenty of Congressional apologists for the FBI usurping the role of the prosecutor. And also amazing how many in Congress think firing Comey stops an investigation.
Wray did okay during the inquisition. He was getting tired near the end of it.
