From coast to coast.

Millions protest against Trump: "No kings!"

"No kings","No kings".

That's the slogan for the nationwide protests taking place in the USA this weekend. Behind the protests is a coalition of organizations and unions.

The protesters are against President Donald Trump's rule, which they believe is becoming increasingly militarized and authoritarian. The background is, among other things, the raids by the immigration agency ICE and Trump's sending the military to several Democratic-led states.

"The president believes he has unlimited power. But in America we have no kings and we will not surrender to chaos, corruption and cruelty," the No Kings website states.

Millions of people are expected to participate.

Dress in yellow – and animal costumes

Pictures taken from the air show huge crowds in New York, Washington and Boston, among others.

Outside Atlanta, at least 10,000 people had gathered in a field to march toward the city.

In New York, around 100,000 people showed up, according to the city's police department.

And from the capital, Washington DC, reports are coming that over 200,000 people gathered near the Capitol to protest, writes The Guardian.

Some carry signs with crossed-out royal crowns. Several wear yellow clothing – a color that organizers say symbolizes unity and has been used in other nonviolent resistance movements.

A lot of people have dressed up.

Chickens, frogs, unicorns and dinosaurs are seen walking with placards.

“I think the costumes really show that we’re not violent, we’re just trying to support our movement. I think it’s hard to see a country you love degenerate into fascism,” says Hailey, 24, who came to the New York demonstration dressed as a frog.

Soldiers ready

In several Republican-controlled states, soldiers from the National Guard are on standby, writes BBC. But it is unclear how much they will be visible during the protests.

A demonstration will be held near Mar-a-Lago – Trump's residence in Florida, where the president is also staying this weekend.

Celebrities get involved

Several celebrities have used their social media channels to encourage people to participate in the protests.

Actor Robert de Niro posted a short video earlier this week.

"We've had two and a half centuries of democracy... often challenging, sometimes messy, always necessary. Now we have a would-be king who wants to take it away from us: King Donald the First," he says.

Even in Europe, people have taken to the streets in Berlin, Madrid, Rome and Malmö to show solidarity.

Criticism: “Hate America demonstration”

It is no coincidence that the protests are happening now. Many Americans are frustrated that the entire government has been shut down because the parties have not been able to agree on the state budget.

Trump supporters are accusing the protesters of being allied with the left-wing movement Antifa. Republican congressmen are calling the protests a “hate America demonstration.”

And Trump himself waves the protesters away.

– You know, they refer to me as a king. I'm not a king, the president told Fox News ahead of the protests.
