White House chief of staff Susie Wiles and FBI Director Kash Patel supervised an investigation into leaks about safety concerns involving the Qatari-donated Air Force One jet, during which some officials' cellphones were confiscated.

In addition to asking for cellphones, investigators sought information from officials who traveled with President Donald Trump or played a role in his trip to the NATO summit in Turkey, including personnel across multiple agencies, CNN reported Wednesday, citing two sources familiar with the matter. Not all officials who were asked to turn over their devices did so.

The sources said Patel, who had been preparing to travel to Chicago, was diverted to the White House on Friday to take a hands-on role in directing the investigation. The inquiry became public early the next morning when The New York Times reported that the Justice Department issued subpoenas to four of its journalists who reported on security concerns surrounding the new plane.

The subpoenas sought to compel the reporters to testify before a federal grand jury in Manhattan this week, the Times reported. It added that federal agents delivered some of the subpoenas to the reporters at their homes.

Patel used an office next to Wiles' for roughly seven hours as the two established what one source referred to as a "war room" in the West Wing, according to CNN.

"Leaks that jeopardize the safety of the President, his staff, and the traveling press pool are dangerous and a threat to national security," a White House official told Newsmax. "The White House takes these leaks seriously and will do everything legally to ensure the individual or individuals are caught and it does not happen again."

Trump used the approximately $400 million Qatari-donated Air Force One jet to travel to the NATO summit in Turkey but left on an older Air Force One aircraft after receiving updated security assessments, according to CNN.

At a postsummit news conference, he downplayed reports about security deficiencies with the new jet, saying it was going to "a couple of bases" in Europe "so the soldiers can see it, because it's truly magnificent."

According to CNN, after Trump traveled to Turkey, the security assessment changed, and Wiles briefed Trump that he would need to leave the country aboard the older aircraft. The Qatari-donated plane had been quickly retrofitted with defensive capabilities but was not as secure as the older aircraft, which had been built specifically to protect presidents during overseas travel.

Trump switched back to the new jet at a secure U.S. base in the United Kingdom before returning to Washington, D.C.
