CNBC Anchor Complained NBCUniversal C.E.O. Pressured Her for Years

Ms. Gamble, 41, is a journalist based in Abu Dhabi, the United Arab Emirates. She has interviewed major world figures including President Vladimir Putin of Russia, King Abdullah II of Jordan and Chancellor Olaf Scholz of Germany, and she has worked for CNBC for more than a decade in the Middle East and London, where she met Mr. Shell.

The complaint alleged that Mr. Shell invited Ms. Gamble to dinner in London — the complaint does not say what year — when she was a relatively junior producer and he was the head of NBC International. After the dinner, Mr. Shell accompanied Ms. Gamble back to her hotel and he pressured her to start a sexual relationship but was rebuffed.

Ms. Gamble did not work for the division Mr. Shell oversaw when they met, according to a person familiar with the matter.

Ms. Gamble and Mr. Shell eventually did begin a sexual relationship, according to the complaint, after it became clear to her that rebutting his advances would probably damage her career. The complaint said that Mr. Shell continued to use his position of power at NBCUniversal to pressure her for sex while pursuing her in London, New York and Dubai.

Mr. Shell pursued Ms. Gamble on and off over a period of years over text and email, according to two people familiar with their correspondence, and Ms. Gamble turned over those messages to the company as part of its investigation.

Elsewhere in the complaint, Ms. Gamble alleged specific instances of discrimination and inappropriate behavior toward numerous women at CNBC. In one instance, Ms. Gamble describes a manager calling her a vulgar epithet for women in front of her co-workers for raising concerns about bullying behavior from another journalist. In another, she alleges a co-worker berated her for ending an interview early, using coarse language, and snapping at her for rewriting headlines that she had to read on air.

Ms. Gamble filed the complaint after CNBC did not renew her contract this year. A person familiar with Ms. Gamble’s thinking said that her decision to file the complaint, which she had considered for years, was also based on frustration with what she viewed as a toxic culture of harassment and bullying at CNBC. Axios earlier reported on those aspects of the complaint.
