The Trump administration is working to halt training exercises designed to educate federal employees about white privilege and other issues, a source told Fox News.

The revelation came after Discovery Institute researcher Christopher Rufo told “Tucker Carlson Tonight” that “critical race theory” had become the default ideology of the federal government. He pointed to several of his own findings, including that Sandia National Laboratories — which designs nuclear weapons — held a mandatory retreat titled, “White Men’s Caucus on Eliminating Racism, Sexism, and Homophobia in Organizations.”

A petition calling for Trump to end this practice in the public sector has been being spread across the web, and needs 100,000 signatures for the White House to consider.

In response to Rufo’s claims, a senior administration official told Fox News that the administration was doing everything they could to stop those types of trainings for federal employees.

Rufo specifically called on President Trump to sign an executive order banning critical race theory-type trainings from the federal government.
