Longtime feminist activist Gloria Steinem gave one of the earliest big-name speeches at the Women’s March on Washington, strongly rebuking President Donald Trump.

Steinem slammed Trump for his divisive rhetoric, which has at one point or another offended women and practically every minority group in America. “The Constitution doesn’t begin with, ‘I, the president,’” Steinem said. “It begins with, ‘We, the people.’ So don’t try to divide us!”

Steinem specifically slammed Trump’s previous proposal, which he has since dropped, to force Muslims to register in a government database. “If you force Muslims to register, we will all register as Muslims,” she declared.

She also praised some of the politicians that have inspired organizers of the Women’s March, including the Obamas, Hillary Clinton, and Bernie Sanders. “They are with us,” she said.

And she bragged about how attendance for the Women’s March was so far looking much better than turnout for Trump’s own inauguration. “I have met the people, and you are not them. We are the people,” she said. “Just this march in Washington today required 1,000 more buses than the entire inauguration.”
