Joe Bidens daughters DIARY has been authenticated, page-7

Two different things.

Yep the Diary exists.

The supposed contents previously released has not been "authenticated to be true".

"...If it isn't authentic how could a lady be charged with stealing it?..."

You don't need to be an Einstein to know they are two different things, as in the Diary exists and the information purported to be from the Diary hasn't been authenticated.

Must be hard being a Trumpy.
