 The White House says President Joe Biden is withdrawing a series of executive orders that ought to ban new downloads of WeChat and TikTok and ordering a new Commerce Department review of security concerns posed by those apps. The administration of former President Donald Trump had attempted to block new users from downloading the apps and ban other technical transactions that Chinese-owned TikTok and WeChat both said would effectively block the apps used in the United States. The courts blocked those orders that never took effect.
