The Guy Goes but His Love Bunny Stays? Multiple Wives? Makes No Sense...

 Ms. Gollust said she would remain at CNN.

At NBC — where Mr. Zucker was first president of its entertainment division, and then chief executive of NBCUniversal — Ms. Gollust took on significant responsibilities. She oversaw communications for NBC News, MSNBC, CNBC and the Weather Channel, and then moved into an executive communications role at NBC Universal.

In 2011, after Mr. Zucker was ousted from NBC Universal, he became an executive producer for a new daytime talk show being developed for Ms. Couric at ABC. Mr. Zucker made a “huge push to bring on” Ms. Gollust to handle public relations for the show, Ms. Couric wrote in her book. She recalled telling Mr. Zucker that she had already hired someone for the role, and that Mr. Zucker urged her to meet with Ms. Gollust anyway.

“I had to wonder why Jeff was angling so hard to bring Allison on board,” Ms. Couric wrote. “She and her husband and kids had moved into the apartment right above Jeff and Caryn’s — everyone who heard about the cozy arrangement thought it was super-strange. By that point, Caryn had become a close friend and it made me really uncomfortable.”

Ms. Couric wrote that she told Ms. Gollust that there was no job for her.

By late 2012, Ms. Gollust had signed on to become communications director for Andrew Cuomo, then New York’s governor.

Shortly after she started working with Mr. Cuomo, Mr. Zucker was named the next president for CNN. Ms. Gollust left her job with Mr. Cuomo after four months to rejoin Mr. Zucker and lead communications for CNN.
