Chris Cuomo
WarnerMedia's CEO also said Allison Gollust, who had a secret relationship with Zucker, had resigned on Tuesday.
An investigation revealed the former anchor played a bigger role in helping his brother, then-Gov. Andrew Cuomo, deal with sexual misconduct allegations.
"I am extremely grateful for the support I have received from SiriusXM throughout my time there," Cuomo wrote on Twitter.
The network was aware of the allegation just days before the anchor was fired for helping his then-governor brother defend himself against misconduct claims.
WHAT'S HAPPENING
Cuomo has been terminated "effective immediately" for his involvement in helping his brother, former Gov. Andrew Cuomo, respond to sexual misconduct allegations, CNN said.
Brian Stelter, the cable network's media reporter, said it's possible Cuomo could be back on the air next month.
The star anchor said he understands why he had to leave the network and that he never meant to "compromise" his colleagues.
The Fox News host defended the CNN newsman for helping brother Andrew Cuomo fight sexual misconduct accusations.
"If some news channel intern did what Chris Cuomo did they'd have been fired one second after these docs were published," one journalist noted.
"The documents, which we were not privy to before their public release, raise serious questions," the network said.
