(CNN) - The national war of words between Sarah Palin and the man who was nearly her son-in-law flared up once again on Wednesday, as Levi Johnston accused Palin of frequently describing her son Trig, who has Down syndrome, as "retarded."
Palin's team shot back in an e-mail to reporters, calling the claim "inflammatory" and accusing CBS - the network that aired Johnston's latest interview - of "continually providing a forum to propagate lies."
"We have purposefully ignored the mean spirited, malicious and untrue attacks on our family," Palin spokeswoman Meg Stapleton said in the e-mail, on which Palin's lawyer Thomas Van Flein was copied. "We, like many, are appalled at the inflammatory statements being made or implied. Trig is our 'blessed little angel' who knows it and is lovingly called that every day of his life. Even the thought that anyone would refer to Trig by any disparaging name is sickening and sad."
Stapleton went on to blast Johnston, who is preparing for a photo shoot with Playgirl magazine, as desperate for publicity.
"Consider the source of the most recent attention-getting lies - those who would sell their body for money reflect a desperate need for attention and are likely to say and do anything for even more attention," she said.
Johnston first made the accusation in a September interview with Vanity Fair and expanded on his claim about Trig during an appearance on the CBS "Early Show" on Wednesday.
