The Office of Management and Budget calls the guidance, issued on Monday, a “critical step forward in addressing the risks presented by the app to sensitive government data,” as reported by Reuters.
Some agencies, including the Departments of Defense, Homeland Security and State, already have restrictions in place; the guidance calls on the rest of the federal government to follow suit within 30 days.
The White House already does not allow TikTok on its devices.
“The Biden-Harris administration has invested heavily in defending our nation’s digital infrastructure and curbing foreign adversaries’ access to Americans’ data,” said Chris DeRusha, the federal chief information security officer.
“This guidance is part of the administration’s ongoing commitment to securing our digital infrastructure and protecting the American people’s security and privacy.”
The guidance was first reported by Reuters.
Congress passed the No TikTok on Government Devices Act in December as part of a sweeping government funding package.
The legislation does allow for TikTok use in certain cases, including for national security, law enforcement and research purposes.
TikTok spokesperson Brooke Oberwetter said Monday, “The ban of TikTok on federal devices passed in December without any deliberation, and unfortunately that approach has served as a blueprint for other world governments. These bans are little more than political theatre.”
China said the United States was overstretching the concept of national security.
“We firmly oppose those wrong actions,” Chinese foreign ministry spokesperson Mao Ning said at a regular news briefing on Tuesday.
House Republicans are expected to move forward on Tuesday with a bill that would give President Joe Biden the power to ban TikTok nationwide.
The legislation, proposed by House foreign relations committee chairman Mike McCaul, looks to circumvent the challenges the administration would face in court if it moved forward with sanctions against the social media company.
If passed, the proposal would allow the administration to ban not only TikTok but any software applications that threaten national security.
Bob Menendez, his counterpart in the Senate, did not shut down the idea of the chamber taking up a proposal that would empower Biden to take action against TikTok, saying it was “certainly something to consider.”
On Monday, Canada announced it was joining the U.S. in banning TikTok from all government-issued mobile devices.
“I suspect that as government takes the significant step of telling all federal employees that they can no longer use TikTok on their work phones many Canadians from business to private individuals will reflect on the security of their own data and perhaps make choices,” Canadian Prime Minister Justin Trudeau told reporters after the announcement.
