Politico reported that the National Security Agency warned the Trump Administration against using their personal emails.

Politico reported in 2017 that the National Security Agency warned Trump White House officials against using their personal emails and cell phones, a practice that "could make them vulnerable to espionage by Russia, China, Iran and other adversaries."

The outlet reported that those briefings occurred "soon after President Donald Trump was sworn into office on Jan. 20, and before some top aides, including senior adviser Jared Kushner, used their personal email and phones to conduct official White House business".

Trump administration officials were told that they should assume their personal communication devices were already hacked and anything on those devices was already known to enemy intelligence agencies.

If Kushner did not adhere to the security precautions, it could lead to a significant security breach, the officials said, given his access to President Donald Trump and unique portfolio of responsibilities.

If Jared Kushner's devices were compromised (which is assumed they were) it means foreign intelligence agencies were likely listening to meetings of serious importance.

“Jared is probably one of the top five or 10 targets in the U.S. government because of his access to the president and because of the portfolios he’s been given,” said Richard Clarke, a former top cybersecurity advisor to three presidents. “It’s a pretty safe bet that his personal devices have been compromised by foreign intelligence services. And therefore there is some risk that meetings he attends are compromised too.”

Politico had reported previously that "that Kushner and his wife, Trump’s daughter Ivanka, created a private family domain before Trump took office. Kushner used it to communicate with top White House officials in early 2017."

The news outlet had also reported "that at least five Trump aides used personal email for public business, including Ivanka Trump and economic adviser Gary Cohn, and that [former White House chief of staff Reince] Priebus tried unsuccessfully to stop White House aides’ rampant use of cellphones for official business."
