The Federal Communications Commission is opening an investigation into Walt Disney (NYSE:DIS) and its ABC network, the FCC chief said in a social media post.

"While Disney started as an iconic American company, it recently went all in on DEI [Diversity, Equity and Inclusion practices]," FCC Chairman Brendan Carr said in a post on social media network X, noting that he asked the FCC's Enforcement Bureau to open a probe.

"I am concerned that their DEI practices may violate FCC prohibitions on invidious forms of discrimination," he added.

In an attached letter to Disney (NYSE:DIS) CEO Bob Iger, Carr said that he wants to ensure Disney and ABC have not violated equal employment opportunity regulations.

"As you know, Disney started out a century ago as an iconic American company," Carr tells Iger in the letter. "For decades, Disney focused on churning out box office and programming successes. But then something changed. Disney has now been embroiled in rounds of controversy surrounding its DEI policies."

The Communications Act and FCC rules prohibit regulated entities like ABC from "discriminating on the basis of race, color, religion, national origin, age, or gender," Carr said in the letter.
