(AP) President Donald Trump’s travel ban barring citizens of seven predominantly Muslim nations entry into the U.S. has sparked protests around the country Saturday night and early Sunday morning.

At Seattle-Tacoma International Airport, about 3,000 protesters holding signs and chanting “no hatred, no fear, immigrants are welcome here” and “let them in” gathered Saturday evening and continued demonstrating into early Sunday morning.

Aayah Khalaf, a Muslim American, was sitting at home watching the protest on television when she and her friend studying from Egypt decided to join the rally. It was her second time joining a protest. The first one was the Women’s March.

“It’s not just against Muslims. It against environmental rights and human rights overall. I think everybody has to stand up against this,” said Khalaf, 29.

The Port of Seattle Commissioners, which oversees the airport, issued a statement criticizing the executive order.

“The Port of Seattle Commissioners, Tom Albro, Courtney Gregoire, Stephanie Bowman, Fred Felleman and John Creighton are here today to express our concerns over the immigration ban executive order that was issued late last night. As the government that operates this airport, this executive order runs counter to our values. America is great because we are a land of immigrants and that is what made us great to begin with,” the statement said.

Cries of “Let them in!” rose up from a crowd of more than 2,000 people protesting at John F. Kennedy Airport, where 12 refugees were detained Saturday. Celebrities including “Sex and the City” actress Cynthia Nixon joined the demonstration. “What Donald Trump did in the last 24 hours is disgusting, disgraceful and completely un-American and I’m here in protest,” said protester Pamela French. The agency that runs the airport tried to restore order by shutting down the train that runs to airport terminals. Gov. Andrew Cuomo, a Democrat, reversed that decision, saying people had a right to protest. “
