Besides the obvious hypocrisy, pointed out with characteristic aplomb by Andrew McCarthy, something else, likely more important, was at play.
The media (and the Democrats, of course) deliberately missed the point because you would have to be seriously intellectually challenged not to get why Trump might have been hesitant or ambivalent about going to the FBI. These days only a total dimwit would unquestioningly trust the supposed "world's greatest law enforcement agency." The FBI is under a dark cloud.
The litany of personages who have recently left or been expelled from that organization is long and getting longer. As is well known, it's under investigation for its practices during and before the Mueller probe, via the inspector general and recently-appointed U.S. Attorney John Durham, who is famed for prosecuting FBI agents with ties to the Boston mob. All this is being supervised by AG William Barr.
A weaponized arm of the Deep State, always has been. Protecting the nation from domestic terrorism... not so much.
