Dark money group America First Policies is running a pro-Trump polling operation. Here is an inside look at its secretive work.

America First Policies, a nonprofit group with close ties to President Donald Trump, has hired Trump’s pollsters to conduct a wide range of political polling and research that experts say resembles the kind of expensive work the Republican National Committee has performed for prior GOP administrations.

Such a practice breaks with decades of tradition and raises concerns about potential coordination between the pro-Trump dark money group, the White House and the RNC. America First Policies and the RNC have denied coordinating. The White House did not respond to multiple requests for comment.

Over the past six months, CNBC has obtained more than 50 documents through an obscure portal on the America First Policies website. CONT.
