Huge crowds mustered in cities for “No Kings” protests on Saturday in response to what organizers call overreach from President Donald Trump.

A chant comparing Immigration and Customs Enforcement (ICE) to the Ku Klux Klan was heard in the streets of New York City Saturday amid the global "No Kings" protests being held to challenge President Donald Trump.

Speaking at a "No Kings" rally in Washington, D.C., Bill Nye, the former host of "Bill Nye the Science Guy," urged lawmakers to “stop the abuses of this petulant president [Trump] and his circle of sycophants,” declaring, “No thrones, no crowns, no kings."

More than 2,500 “No Kings” rallies were planned around the country, with organizers citing rising authoritarianism and militarization under the Trump administration. The first round of “No Kings” protests in June drew about 5 million people. See some of the images from Saturday’s events below.

The demonstrations against the US president - which Republicans had called "hate America rallies" - were boisterous but peaceful.

A second round of "No Kings" demonstrations are planned for Saturday, Oct. 18. Here's where events are scheduled in Washington state.

The "No Kings" organizing group said rallies are expected in hundreds of locations across the country on Saturday in cooperation with civil rights groups and other organizations. The movement said it mobilized millions of people at its protests in June. Here is the latest map from their website showing where rallies are planned:

With chants, costumes and colorful signs, Washingtonians raised their voices against Trump's hard-line policies on immigration, the federal budget and more.

The demonstrations follow a wave of protests in June that organizers say drew more than 5 million people in cities across the country.
