CBS News has reportedly fired an employee said to be involved in the leak of a video showing ABC “Good Morning America” anchor Amy Robach criticizing her network for not running a story on Jeffrey Epstein three years ago.

ABC News executives believe they know who accessed the Robach video and that the former employee was now at CBS, according to a report Thursday by journalist Yashar Ali, who noted that it was unclear whether the employee was responsible for leaking the video.

"Two sources familiar with the matter tell me that CBS News has fired the staffer in question," Ali tweeted with an accompanying story. "This comes after ABC informed CBS that they had determined who accessed the footage of Amy Robach expressing her frustrations about the Epstein story."
