Days after recent revelations that Jared Kushner, a presidential advisor and the president's son-in-law, had set up a personal e-mail account to conduct White House business, someone with access to that domain (ijkfamily.com) changed the domain’s mail exchange (MX) records so that they now point to a Trump Organization server.

The move, which was first reported by USA Today on Tuesday, provides clear evidence that there is not quite as much separation between the Trump Organization and the Trump White House as previously indicated.

The MX records show that they were changed from Microsoft to the Trump Organization shortly after public scrutiny of Kushner’s e-mail account intensified. A domain’s MX records specify which mail servers are allowed to send and receive mail for that domain.

On Monday evening, Politico also revealed that a third e-mail account on that domain existed—beyond one for Kushner and his wife, Ivanka Trump—which sometimes included correspondence of "nonpublic travel documents, internal schedules, and other White House materials."

On September 24, Abbe Lowell, Kushner’s attorney, acknowledged to Politico that his client does use the account for official “White House business,” but he said that e-mails from that account were relatively few. “These are usually forwarded news articles or political commentary and most often occurred when someone initiated the exchange by sending an e-mail to his personal, rather than his White House, address,” Lowell said. That same article noted that “there is no indication that [Ivanka Trump] used her account to discuss government business.” Lowell did not immediately respond to Ars’ request for comment.

Before her father’s inauguration in January 2017, Ivanka Trump wrote in a public Facebook post that she would “no longer be involved with the management or operations” of the Trump Organization or the Ivanka Trump fashion brand.

As Ars noted last month, Trump called his rival, Hillary Clinton, “Crooked Hillary” during the 2016 presidential campaign and afterward because she used private e-mail to conduct government affairs when she was secretary of state. The Justice Department did not press charges against Clinton, although Trump vowed to if he was elected.

The Trump Organization did not immediately respond to Ars’ request for comment, but it did provide this response to CNN.

This response makes little sense, as MX records cannot be falsified.

UPDATE 7:08pm ET: While Lowell did not respond to Ars' questions, he did e-mail us the exact same statement that was sent to CNN. We challenged the statement and said that it did not hold water, and we asked to be put in touch with any relevant IT staff. We will update this post if further responses come in.

UPDATE 7:15pm ET: We confirmed our findings with Matt Blaze, a computer science professor at the University of Pennsylvania. He verified that the trumporg.com mail servers are configured to accept mail for the ijkfamily.com domain name.

"No one can claim that this was just the DNS for ijkfamily being hacked," he said via Twitter DM. "The trump.org mail server would have to have been hacked too. Or (more likely), it was just configured that way.”
