Among the nearly 20,000 internal emails from the Democratic National Committee, released Friday by Wikileaks and presumably provided by the hacker “Guccifer 2.0,” is a May 2016 message from DNC CFO Brad Marshall. In it, he suggested that the party should “get someone to ask” Democratic presidential candidate Bernie Sanders about his religious beliefs.

The email was sent to DNC Communications Director Luis Miranda and Deputy Communications Director Mark Paustenbach. It’s unclear who the “someone” in this message could be — though a member of the press seems like a safe bet. A request for comment sent to Marshall was not immediately returned.

[UPDATE at 1:03 p.m. ET: Marshall emails to say “I do not recall this. I can say it would not have been Sanders. It would probably be about a surrogate.” We have asked him who that surrogate could possibly be.]

And although Sanders is not mentioned by name, he was the only Jewish candidate from either party — an apparent weakness that Marshall believed the party could exploit in favor of Hillary Clinton.

It is also unclear why the Democratic National Committee, which isn’t supposed to favor one Democratic candidate over another until they receive a nomination, would have attempted to subvert the Sanders campaign on the grounds that “he is an atheist.”

A reply to Marshall’s email from DNC CEO Amy Dacey read only “AMEN.”

[UPDATE at 5:10 p.m. ETIn a private message, the hacker “Guccifer 2.0” confirmed he provided the email trove to Wikileaks, saying “Yeah man, as I promised.”]
