Immigration protesters ambushed Rep. Paul D. Ryan Thursday at a book signing in Thornton, Colo., asking about the lack of congressional action on immigration.

Ryan was confronted by Greisa Martinez, a national organizer with United We Dream.

“I do not understand why you want to deport me and my mother? Why didn’t your party pass immigration reform when you had the opportunity,” she loudly questioned, mentioning the deferred action for childhood arrivals program. “Rep. Ryan, My name is Greisa Martinez I am DACA-mented and I am hear to stay!”
