Phones have been a bit of an issue in the White House. In October, Politico reported that White House Chief of Staff John Kelly had been using a compromised personal phone, which might have been breached by outside parties as early as December of last year. And President Trump has also come under fire for using his personal, unsecured smartphone over his government-issued one as well as for discussing classified material in the public Mar-a-Lago dining room while guests snapped photos with their phones and his dinner guests and aides reviewed classified documents while using their phone flashes as reading lights.

The proposed ban on personal phones hasn't been adopted yet and as Bloomberg reports, if it is enacted, it's currently unclear when that would happen and to whom it would apply.
