CNN Worldwide President Jeff Zucker has resigned. The reason for his resignation was his long-standing affair with colleague Allison Gollust, CNN's director of marketing.

"As part of the investigation into Chris Cuomo's tenure at CNN, I was asked about a consensual relationship with my closest colleague, someone I have worked with for more than 20 years," Zucker told employees in a memo. "I acknowledged the relationship evolved in recent years. I was required to disclose it when it began but I didn't. I was wrong. As a result, I am resigning today," Zucker said.

Zucker did not name a colleague but the relationship in question is with Allison Gollust, who remains at CNN.

"Jeff and I have been close friends and professional partners for over 20 years. Recently, our relationship changed during Covid. I regret that we didn't disclose it at the right time," Gollust wrote in a note.
