The day after the inauguration of President Donald Trump millions of women organized in cities around the world on Saturday to express their disapproval of the new administration. From Washington D.C. to Los Angeles, from Chicago to London, from Sydney, Australia, to Paris, France, protesters are marching, united in their shared belief that womens rights shouldnt be ignored.

A long list of politically active A-listers hit the pavement in solidarity with the cause to lend their voices to the growing chorus of citizens whove vowed to resist Trumps presidency. Stars like Amy Schumer , Lena Dunham, America Ferrera , Chelsea Handler, Jessica Chastain and Katy Perry were all in attendance to march under the banner of human rights for women, immigrants, the queer community and more.

Much of the celebrity activity was centered around Washington D.C., where an Artist Table was formed , featuring a diverse group of celebrities who will participate in and join in solidarity. Ferrera is serving as chairwoman for the group and delivered impassioned remarks to the crowd on Saturday morning.

Perry, who was one of the biggest supporters of Trumps Democratic opponent Hillary Clinton, shared an old photo of herself and sister Angela on social media before joining the crowd in D.C.
