That depends on what the meaning of "is" is.
CLASSIC weasel words. OF COURSE Bolton didn't share it with anyone.
Did someone with access to the proofs and operating under Bolton's direction do so?
Without a doubt.
The one constant from the Democrats (and Romney) from the very very beginning of this farce has been, "We have to hear from John Bolton".
Now we know why.
Its because he was fired. They have also demanded to hear testimony from Mick Mulvaney, but he hasnt been fired so they dont expect much from him.
