AT&T Inc. on Tuesday confirmed that it has fired Aaron Slator, a president who became the subject of a $100 million discrimination lawsuit for using his work phone to send racially offensive images. “There is no place for demeaning behavior within AT&T and we regret the action was not taken earlier,” the company said.

The images in question were found on Slator’s phone by an assistant who was asked to transfer data to a new phone, according to the lawsuit filed Monday by Knoyme King, a 50-year-old Black woman who worked for Slator.
