Except that still is taken from the video linked to the article in this post. She moves her hand away and you can plainly see 'Roy' and that's all.
The Hot Air article doesn't help.because it has the transcript of the Hannity interview. Moore says on Hannity he was friends with her parents, knew Debbie to be a good girl, but didn't 'remember any specific dates.'
Some time later, he goes on to say at two different appearances he didn't know any of the women and didn't date any of them. At the very least, he's contradicted himself on Gibson. That wasn't wise, because it brings his credibility on the others back into question.
By the later interviews the talk had shifted to "underage" girls. In Alabama that means under 16, but the media have been loosely describing people as "children", even into their twenties, when it suits their purpose.
How many other graduating seniors got the cards? Were they just an office thing, sent out to the whole class? (That isn't that uncommon, not in election years, and such a card would likely have gone out to an 18 or 17 year old at graduation).
I have sent cards to friends' kids when they graduated, too, with a small gift (a little money), usually in reply to an announcement, and definitely not implying any carnal knowledge or deeper relationship. So the card may not prove anything at all. I couldn't tell you who I had sent those cards out to at this point, and might not recognize the names after all these years.
At most, it proves she was sent a card.
