Charles Callaghan, a Republican from Ponte Vedra, received one of the fraudulent letters Saturday.

“Basically, when I read the letter, I got the impression that I was not going to be able to vote, because my citizenship was being questioned,” Callaghan told The Daily Caller. “I wasn’t quite sure why it would be, because I was born in the United States, and I’ve always been a United States citizen, and nothing has changed in my life … that would cause my citizenship to be called into question.”
