No so much disprovable as there's just no sign of it anywhere other than as a forwarded image. Senators release these things as publicity things, so the fact that nothing turns up in Google (and her name is misspelled) makes it feel too good to be true. Would be fine (somewhat) to learn it's real. 

Feel free to disprove it, I wouldn’t be mad.

I kinda feel like she'd know how to spell her own name, and that this would be somewhere on her site.
