Gordon joined the Mad Men team in 2007 as Weiner’s assistant, and says the experience was initially a positive one.

“I felt excited to be able to be so close to making – what I thought at the time – was such a great show. And he [Weiner] championed me. It was extremely satisfying,” she recalls. The Information quotes Gordon’s colleagues at the time, who say that Weiner “respected Gordon tremendously” and would often ask her opinion on various storylines for the season two of the show.

He then offered her the chance to co-write the finale, an opportunity he’d also given to his previous writer’s assistants. It was on a night when they were working together on revisions to the script that Gordon claims Weiner said he wanted to see her naked. She says she brushed off the comment, and they continued to work that night to finish the episode.

Gordon says she shared her experience with several unnamed people on the show, who confirmed this when asked by The Information. However, she was reluctant to reveal her experience publicly – until now.

Like so many have said, she initially felt that speaking out about what happened to her would harm her career, and prevent her from getting a credit on the episode she worked on with Weiner. “I thought, ‘I can’t do anything to jeopardize,’” she says. “I need this credit. I saw no value to speaking out. So I did what I thought women were supposed to do.”

But she says the alleged incident changed things on the show, and Gordon could no longer see a way forward in working with Weiner. “I did my best to play along but couldn’t divorce him from the comment, and I lost respect,” she says. “I couldn’t in good conscious support him the way I did the previous year.”
