Right. I interned in a Critters office for a couple of semesters in college. They never sign anything. They don't write much themselves either. Although I'm pretty sure if Pelosi didn't write this she read it carefully before approving it.
I just thought of something...maybe she did sign this letter and that's why the signature looks off.
When I would sign for the leagle beagles in my office, I had to note with my initials. But hey, they’re congress! They can do any damn thing they want.
