A former CIA contractor who helped fight off terrorists in Benghazi four years ago was in the Bay Area on Sunday. Kris Paronto shared his story in a book, which was released into a movie earlier this year.

Paronto spoke to a group of Marin County Republicans about what happened in the critical moments before Piedmont native Chris Stevens and three other Americans lost their lives.

“I was the ranger,” Paronto said.

Paronto is one of the few people who really knows what happened in Benghazi four years ago.
