Six former employees at the anti-Trump Republican group the Lincoln Project went after its leaders Thursday night, demanding to be released from their nondisclosure agreements (NDAs) so they can talk openly about John Weaver, a now-departed co-founder who has been accused of sexually harassing young men.

The organization, amid receiving massive criticism for the allegations against Weaver, announced Thursday night that it would be hiring an outside investigator to review his tenure at the Lincoln Project.

Leaders of the Lincoln Project say that they were unaware of Weaver’s conduct until recent reports detailed these allegations.

In an open letter published by The New York Times, the six unnamed former employees and associates asked that their NDAs be waved, saying that they wanted to be allowed to disclose information “that would aid the press, public and our donors in answering questions relevant to the public interest.”

“Tonight, in light of recent events, news reports and statements from the Lincoln Project, we call on the remaining leadership of the Lincoln Project to release us all and all others from all Non-Disclosure Agreements (or other contracts), without precondition, regarding (a) harassment perpetuated by John Weaver that we have experienced or witnessed (b) knowledge of harassment of others by John Weaver (c) any other information specific to the John Weaver situation that would aid the press, public and our donors in questions relevant to the public interest, and to the interests of the Lincoln Project’s many loyal fans and small donors,” the letter reads.

“Recently published stories about the Lincoln Project are filled with inaccuracies, incorrect information, and reliant exclusively on anonymous sources,” the Lincoln Project said in a statement posted to Twitter on Thursday night. “However, there is a central truth in all of them that must be reckoned with and that is John Weaver’s appalling conduct and the abuse he inflicted on people.”

Thus, the organization announced, that it would be retaining a “best-in-class outside professional to review Mr. Weaver’s tenure with the organization and to establish both accountability and best practices going forward for the Lincoln Project.”

At the end of its statement, the Lincoln Project emphasized that “any person who believes they are unable to talk about John Weaver publicly because they are bound by an NDA, should contact the Lincoln Project for a release.”
