(CNN) - Anthony Weiner's communications director apologized Tuesday night for bashing a former intern in a scathing interview laced with four-letter words.
"In a moment of frustration, I used inappropriate language in what I thought was an off the record conversation," Barbara Morgan said in a statement to CNN. "It was wrong and I am very sorry."
Morgan added that she called and apologized Tuesday night to the former intern, Olivia Nuzzi.
Talking Points Memo, a left-leaning news organization, published a report late Tuesday night, quoting Morgan as she responded to a New York Daily News article written by Nuzzi, who described an unflattering account of Weiner¹s New York City mayoral campaign.
"(Morgan) went off on a curse-filled rant about Nuzzi, describing her as a fame hungry 'b**ch' who 'sucked' at her job. Morgan also called Nuzzi a 'sl*tb*g,' 'tw*t,' and 'c**t' while threatening to sue her," the TPM article stated.
In the New York Daily News story about her brief internship on Weiner¹s campaign this summer, Nuzzi wrote about other interns who were on the campaign simply seeking to get access to Weiner's wife, Huma Abedin, in hopes of scoring a connection to former Secretary of State Hillary Clinton, a potential 2016 contender. Abedin is a longtime adviser to Clinton.
Nuzzi also shared a story about Weiner struggling to learn interns' names–despite boasting of his memory skills–and blasted the campaign's professional staff as inexperienced. She belittled Morgan, in particular, saying her last job was a press secretary role for the New Jersey state education commissioner.
"There were a lot of short résumés around the office," Nuzzi wrote. "The candidate sometimes seemed inexperienced, too."
Morgan told TPM that Nuzzi "sucked" at her job and she tried to fire the college student, but Morgan said "she begged to come back and I gave her a second chance." Morgan described at length Nuzzi's work ethic and attitude, saying she sometimes didn't show up for work at all.
"F**king sl*tb*g. Nice f**king glamour shot on the cover of the Daily News. Man, see if you ever get a job in this town again," Morgan said, according to TPM.
The dust-up marks the latest road bump in Weiner's campaign. After admitting last week that he continued to send lewd messages to women after his 2011 resignation from Congress, the mayoral hopeful saw his poll numbers plummet. His campaign manager, Danny Kedem, quit over the weekend, and questions continue to pour in about Weiner's online relationships.
But the former congressman has repeatedly vowed to stay in the race. He reiterated that sentiment in a video released by his campaign Tuesday night.
"I know that there are newspaper editors, other politicians that say, boy I wish that guy Weiner would quit," he said. "You don't know New York. You certainly don't know me. Quit isn't the way we roll in New York City."
