Protesting the direction of the country under Donald Trump, people will gather Saturday in the nation’s capital and communities across the U.S. for “ No Kings ” demonstrations — what the president’s Republican Party is calling “Hate America” rallies.

This is the third mass mobilization since Trump’s return to the White House and it is expected to be the largest.

It comes against the backdrop of a government shutdown that not only has closed federal programs and services, but is testing the core balance of power as an aggressive executive confronts Congress and the courts in ways that organizers warn are a slide toward American authoritarianism.
