Muslims across the U.S. fear that they were being targets of surveillance this week as they received automated polling calls asking them to dial one if they were Muslims and two if they were not.

The calls were made as part of a survey by Emerge USA.

The organization created an algorithm to call Muslims for a poll on their views and experiences after the previous U.S. presidential election that led to the victory of Republican Donald Trump, Sarah Cochran, director of its Virginia chapter, said on Wednesday.

Many people have been worried that President-elect Donald Trump was making good on his campaign promise to register all Muslims in the United States.

Cochran said she had to reassure the some call recipients that she was only conducting a poll.

“All of our work is affected, where we can’t get people to participate because they’re afraid,” she said.

One of the call recipient posted on Facebook “Not sure if this is a scam or this is real but I have surely reported and urge you to report as well if you get the same phone call. Welcome to the new world!”

Trump’s choice for national security adviser, Michael Flynn, said in a recent video that Islamism is a “vicious cancer inside the body of 1.7 billion people on this planet and it has to be excised.”
