Not in the slightest, here's what Grusch actually said in his Public Congressional Testimony: "My testimony is based on information I have been given by individuals with a longstanding track record of legitimacy and service to this country — many of whom also shared compelling evidence in the form of photography, official documentation, and classified oral testimony."
I personally don't believe photos are first hand evidence if hes just observing them after the fact. You could argue he was a first hand eyewitness to the photo existing but not to the contents within the photos.
Now are you upset he maintains a TS/SCI to this very day? That's magnitudes more sensitive than yours right?
