Celebrity activists Jennifer Lawrence, Brie Larson, Amy Poehler, Gloria Steinem and Lena Dunham have recorded a video message in support of Planned Parenthood, urging people to speak out and contact their senators to protect access to the reproductive health care service in the US.

The video, released through Lena Dunham's online newsletter Lenny Letter, features a mash-up of more than 25 actors, comedians, media personalities and activists who stand with the organisation and against President Donald Trump's proposed health care bill.
