Prosecutors said there could be more arrests coming in the case against a US Treasury Department worker accused of leaking confidential information to a reporter, including about the Robert Mueller probe.

Manhattan federal prosecutor Kimberly Ravener mentioned the potential additional arrests during a court appearance for Natalie Mayflower Sours Edwards, 40, who is charged with using her cellphone to send a reporter information about investigations into Paul Manafort, Rick Gates, Russian diplomats and Russian agent Maria Butina.

When Judge Gregory Woods asked Ravener if a superseding indictment may be filed, Ravener responded, “Yes, your honor. That is possible. The investigation is ongoing.”

Edwards — who lives in Quinton, Virg. and worked in the Financial Crimes Enforcement Network of the Treasury Department — is charged with conspiracy and unauthorized disclosures of Suspicious Activity Reports, which alert banks to potentially fraudulent transactions.

According to the criminal information filed against Edwards on Wednesday, there was another person in her division — who she referred to as “Enigma” — who had a “wealth of information” and was “willing to verify” facts for the reporter.

Though BuzzFeed was not named by the feds as the organization that published stories using the leaked information, headlines identified by prosecutors allege Edwards gave the information to a reporter for the news site.

After Edwards’ appearance in Manhattan federal court, where she entered a not-guilty plea, her lawyer, Jacob Kaplan, said she intends to fight the charges at trial.

“I don’t think the facts are in dispute. It’s more the significance of them,” Kaplan said adding, “it’s not as simple as the government makes it seem.”

“She is not the first person to be prosecuted for doing the right thing,” Kaplan said.
