CNN fired Chris Cuomo, its most-watched anchor, on Saturday in the wake of revelations he had helped his brother, former New York Governor Andrew Cuomo, while he faced multiple accusations of sexual harassment, doing so in ways of which CNN management had not previously been aware and breaching the traditional ethics of journalism.

The WarnerMedia-backed news outlet, which suspended Chris Cuomo earlier this week, said it would continue its investigation into the work he did for his sibling. The company also said it had retained an outside law firm to conduct its review, citing “additional information that has come to light.” CNN intends to continue to investigate its former employee’s behavior despite its decision.

Late Saturday night, The New York Times reported that Debra S. Katz, an employment attorney representing a former colleague of Chris Cuomo’s from another network, informed CNN of an allegation of sexual misconduct against him. It was not clear that CNN terminated Cuomo because of the new accusation, but it clearly did not help his cause. “Based on the report we received regarding Chris’s conduct with his brother’s defense, we had cause to terminate,’ the network said in a statement. “When new allegations came to us this week, we took them seriously, and saw no reason to delay taking immediate action.” Katz could not be reached for immediate comment.
