WASHINGTON — (CNN) Donald Trump is suing a former campaign aide for $10 million, alleging that the aide breached a confidentiality agreement.
Sam Nunberg, who was fired late last summer from the campaign after racially charged Facebook posts of his surfaced, said he is the former aide who is being sued.
Nunberg’s lawyer, Andrew Miltenberg, told CNN Wednesday that Nunberg is being accused of “violating certain confidentiality provisions by talking about Donald Trump after he was no longer associated with the campaign.”
“It has to do with information within the campaign and relationships between the various people within the campaign,” Miltenberg said, adding that he would not elaborate further.
Miltenberg also said the Trump camp had asked a judge for the arbitration to be sealed. However, some of the exhibits in the suit were not sealed, including three news stories to back up its claim that Nunberg breached his confidentiality agreement, including a New York Post report of two campaign staffers screaming at each other in the streets.
The two other exhibits included Politico articles headlined “Fired Trump aide backs Ted Cruz” and “Trump campaign gets personal,” which included quotes from Nunberg.
Trump Organization General Counsel Alan Garten confirmed the lawsuit but declined to disclose additional details because the suit is “subject to arbitration.”
News of the lawsuit was first reported by The Associated Press.
Trump’s attorneys filed the lawsuit Tuesday in New York Supreme Court.
Nunberg, through his association with longtime Trump political adviser Roger Stone, advised Trump amid his flirtation with a presidential run in 2012. And when Trump began preparing his 2016 bid, Nunberg was again at his side, making early preparations for a potential campaign.
But late last summer, racially charged posts that Nunberg posted on Facebook surfaced and the campaign fired him.
Since then, Nunberg has been fiercely critical of Trump and his campaign staff, particularly now-former campaign manager Corey Lewandowski, who is now a CNN contributor.
The suit comes as Trump is preparing to select a vice presidential running mate later this week.
