The White House is considering banning its employees from using personal mobile phones while at work. While President Trump has been vocal about press leaks since taking office, one official said the potential change is driven by cybersecurity concerns. Bloomberg reports: One official said that there are too many devices connected to the campus wireless network and that personal phones aren't as secure as those issued by the federal government. White House Chief of Staff John Kelly -- whose personal phone was found to be compromised by hackers earlier this year -- is leading the push for a ban, another official said. The White House already takes precautions with personal wireless devices, including by requiring officials to leave phones in cubbies outside of meeting rooms where sensitive or classified information is discussed. Top officials haven't yet decided whether or when to impose the ban, and if it would apply to all staff in the executive office of the president. While some lower-level officials support a ban, others worry it could result in a series of disruptive unintended consequences.
