The American Civil Liberties Union (ACLU) is launching a new project to harness grassroots resistance to President Donald Trump.

The project, People Power, will officially kick off Saturday. It will commence with a livestreamed resistance training to engage volunteers around the country “and take the fight against Donald Trump’s policies not just into the courts, but into the streets,” the organization wrote on its preview website.

Its first effort will be to help cities use their local-level authority to protect undocumented immigrants from deportation and become a network of “freedom cities” capable of withstanding Trump’s ongoing immigration crackdown.

The initiative will give activists a set of “ordinances” to help them pressure local law enforcement to use more lenient immigration policies.

“As Donald Trump does what he does, the greatest political power is in the cities and towns across America,” Faiz Shakir, ACLU’s national political director, told the Guardian on Friday. “Because constitutionally, cities have sovereignty rights unto their own.”
