Brenda Lee, from the Georgia Informer, dragged away by security.
"I said, 'I'll take my chances if (the president) comes by here,'" said Lee, who identified herself as a Roman Catholic priestess who lives in Anaheim, Calif. "He became annoyed that I wouldn't give him the letter."
Lee, who was wearing what she described as a cassock, said she protested when she was asked to leave.
"I said, 'Why are you bothering me?' They escorted me outside the gate," she said.
She said security officers allowed her to return when she promised she would not yell or wave, but then other officers arrived and told her to leave.
"I said, 'I'm not leaving,'" she said. "They tried to drag me out."
Two officers then picked her up and carried her out. An Associated Press photographer photographed the incident.
"I was afraid you could see under my clothes," she said, her voice choking up.
