Trump news - live: Key impeachment witness says president’s ‘bullying’ ended his career as White House to ban TikTok

US president Donald Trump has said he will ban the popular video app Tiktok over security concerns.

The app’s Chinese ownership has raised concerns about the censorship of videos, including those critical of the Chinese government, and the potential for sharing user data with Chinese officials.

Mr Trump said a ban could be implemented on Saturday. On Friday he said he could use emergency economic powers or an executive order to enforce the action, insisting, “I have that authority” before adding: “It’s going to be signed tomorrow.”

The move comes after India‘s government banned a series of apps, including Tiktok, amid claims some of them are using data illegally, and secretly collecting information from people’s phones when they are downloaded.

Meanwhile, Joe Biden is nearing the announcement of his vice presidential choice. The top contenders and their advocates are making final appeals. The leading contenders include California senator Kamala Harris, California Representative Karen Bass and Obama national security adviser Susan Rice.
