Donald Trump isn't going to be happy about this.

Oxfam has rented Trump's childhood home in Queens, and invited refugees who resettled in the U.S. from Syria, Somalia (two of the countries in Trump's proposed travel ban in March), and Vietnam there to share their stories in the president's former home.

The anti-poverty organization says they wanted to send an "unequivocal message" to the US president, who is expected to speak in front of world leaders at the UN's General Assembly in New York, that "refugees are welcome here."

"Millions of families around the world have been forced to flee their homes in order to survive, creating the world’s worst displacement crisis since World War II," Oxfam said in a blog post.

"In this moment, what better place to show world leaders the value of a safe, welcoming home for those fleeing unthinkable situations than the childhood home of the U.S. president."

Trump's 5-bedroom childhood home in Jamaica Estates, Queens was listed on Airbnb at the beginning of August. You can rent it for $725 (£574) a night.

“We wanted to send a strong message to Trump and world leaders that they must do more to welcome refugees,” Shannon Scribner, Oxfam America's acting director for the humanitarian department, told The Associated Press.

One of the refugees, 22-year-old Aiman Ali, who arrived aged only 3 in the U.S. from Somalia via Yemen, said: “Knowing Donald Trump was here at the age of four makes me think about where I was at the age of four. We’re all kids who are raised to be productive citizens, who have all these dreams and hopes.”

“To have someone so outspoken against my community become the president of the United States was very eye-opening and hurtful because I have invested a lot in this country,” she added.
