Perry identifies as a feminist, and appeared in April 2013 in a video clip for the "Chime For Change" campaign that aimed to spread female empowerment. She has also said that America's lack of free health care drove her "absolutely crazy". Following the shooting at the Pulse nightclub in Orlando in June 2016, Perry and nearly 200 other artists and executives in music signed an open letter organized by "Billboard" addressed to United States Congress demanding increased gun control in the United States.
