You have to appreciate the brilliance of the Barr nomination.
POTUS gets rid of Sessions which puts Whitaker in the hot seat. Dems freak out. They don't want Whitaker under ANY circumstances. Now they're eager to confirm whoever they can get who ISNT Whitaker.
Enter Barr.
During confirmation they REPEATEDLY ask him
-Will you let Mueller finish? (yes)
-Will you release report in its entirety (yes)
Per Juan Williams- the public is clamoring for the report, he has an obligation to release it.
Now, when the report is released, and all the DS players are fingered, they only have themselves to blame!
