Now, days later, the Politico is reporting that Ivanka Trump and Jared Kushner's private email use are now the subject of an internal probe by the White House.
Kushner's responsibilities range from serving the president on such issues as China, Syria, Afghanistan and the Middle East, Politico reports, along with infrastructure and innovation.
According to Friday's report, the NSA briefed the new administration officials shortly after the January 20 inauguration and took place in the White House Situation Room because of the sensitive subject matter.
Politico reported earlier Thursday that private email accounts used by the president's daughter Ivanka Trump and her husband Jared Kushner, both top-level advisers, are of particular interest. "We did review this account at the time, and there were no responsive or relevant documents there", Kushner's attorney, Abbe Lowell, told ABC News.
According to Politico, the White House's probe will focus on whether or not any of the private emails were related to the multitude of Russia-related investigations being conducted by Congress and the FBI. There is no evidence that he used it to send classified or sensitive materials.
The administration is scouring the White House server for emails to and from private email accounts of these aides, Politico said, quoting four people familiar with the probe.
"The NSA briefers explained that cyberspies could be using sophisticated malware to turn the personal cellphones of White House aides into clandestine listening devices, to take photos and video without the user's knowledge and to transfer vast amounts of data via Wi-Fi networks and Bluetooth", Politico reports. Nevertheless, a watchdog organization sued the White House over the reported communications. Under the Presidential Records Act, White House correspondence including email is required to be archived.
Mr. Kushner uses his White House email address to conduct White House business.
During the presidential campaign, Trump criticized Clinton for using a private email server as Secretary of State, saying that her decision to do so had put "the entire country in danger".
White House press secretary Sarah Huckabee Sanders told reporters at her daily briefing Monday that White House officials' use of private email is "very limited".
Voter information records held by NY show the presidential adviser - whose portfolio includes everything from seeking peace in the Middle East to reining in the opioid crisis in the United States - was registered as "female".
In addition to the email controversy, Kushner is facing scrutiny over the Trump campaign's alleged collusion with Russian Federation to interfere in the 2016 United States election, which is the subject of the probes in Congress and by Mueller.
