The White House on Monday gave government agencies 30 days to ensure they do not have Chinese-owned app TikTok on federal devices and systems, Reuters reported, citing a guidance memorandum written by Office of Management and Budget Director Shalanda Young.

Young told agencies in the memorandum they will be required to adjust information technology contracts to ensure vendors keep US data safe by eliminating the use of TikTok on their devices and systems.

TikTok has faced rising concerns over national security due to Chinese parent company ByteDance. Both parties in Washington have become increasingly concerned that the Chinese government could use its legal powers to access the user data of American citizens or to spread misinformation.

In August of 2020, then-President Donald Trump signed an executive order giving Americans 45 days to stop doing business with ByteDance, saying Chinese tech operations may be used for spying. The company later announced it will challenge the crackdown on the service in court.

In December, the US House of Representatives Committee on House Administration banned TikTok from all House-managed mobile devices "due to a number of security risks". In addition, more than 20 US states have banned TikTok from government devices.

TikTok has said the concerns are fueled by misinformation. The action does not affect the more than 100 million Americans who use TikTok on private or company-owned devices.
