Microsoft said Sunday it was continuing talks with Chinese-owned video sharing app TikTok to purchase its US operations, following a meeting with President Donald Trump. "Following a conversation between Microsoft CEO Satya Nadella and President Donald J Trump, Microsoft is prepared to continue discussions to explore a purchase of TikTok in the United States," the company said in a statement. Trump has threatened to bar the wildly popular app in the United States, citing security concerns. acb/to
