A media expert warned CBS chief Bari Weiss on Tuesday night that she just set off an "underwater earthquake" at her network by showing veteran journalist Scott Pelley the door.

Brian Stelter, CNN's chief media analyst, told Kaitlan Collins on "The Source" that Pelley's firing likely won't go over well within the CBS newsroom and could lead to a costly legal battle. In the termination letter, CBS Executive Producer Nick Bilton said Pelley was dismissed "for cause," which he can challenge in court.

"This is like an underwater earthquake at CBS News. It's not going to be visible on TV right away, but this is bound to have many ripple effects and maybe a legal battle," Stelter said.

Pelley had been a journalist with CBS News for more than four decades before he was dismissed on Tuesday. His firing came just one day after Pelley confronted CBS News leadership in a staff meeting and accused them of "murdering" the flagship show, "60 Minutes."

"Yesterday’s performative display of hostility — enacted in front of the staff instead of in a civil, private conversation — demonstrated that you have no interest in contributing to the future success of the show, or approaching my new tenure with a mind open to collaboration and progress,” Bolton wrote in the letter.
