Barbara Morgan said she had lashed out in a “moment of frustration” and had thought the conversation was off the record.
“It was wrong and I am very sorry,” she said in a statement to CNN.
According to Talking Points Memo, Morgan, who had been contacted on Tuesday to comment for an unrelated article, blasted Nuzzi for a story the former intern penned criticizing the Weiner campaign.
Morgan said Nuzzi “sucked” at her job and had nearly been fired from the campaign before begging for a second chance. She also laced her rant with offensive and derogatory language, and threatened to sue Nuzzi.
In her story Nuzzi mocked campaign staffers, including Morgan, for having “short resumes” and suggested that many people were only on the campaign to gain favor with Weiner's wife, Huma Abedin, a close aide to potential 2016 presidential candidate Hillary Clinton.
Nuzzi's piece was the latest bit of bad news for Weiner's flagging mayoral campaign, which has been dogged by departing staff and falling poll numbers following his admission that he continued sending sexually-explicit text messages to women even after his resignation from Congress in 2011 for similar behavior.
