This is a classic non-denial denial. He says that the "notion" that his White House would release the information is "offensive". He didn't even bother to directly deny it.
The key word in the sentence is “classified.” In order for it to not be classified, all that needs to happen is that the President declassify it. My prediction is that the report will ultimately state that the information came from the White House, but it wasn’t classified because the President ordered the information be released.
“Non-denial denial”
I noticed that. I wonder if he personally made to calls to friends in the MSM?
He’s also already down to merely defending the (his) motive. All that leaking wasn’t done ‘on purpose’, as in with full knowledge and understanding of the classified nature of the gushers being leaked.
