The President of the United States, Joe Biden, has signed into law a bill seeking to ban social media app, TikTok.

The bill which was earlier passed by the U.S. Congress requires TikTok’s China-based parent company, ByteDance, to sell the app within nine months, or face a ban in the U.S.

Biden signed the bill attached to the $95 billion foreign aid package Congress approved this week that will deliver more funding to Israel, Ukraine and Taiwan, on Wednesday.

Meanwhile, TikTok has vowed to take legal action against the new law.

TikTok spokesperson Alex Haurek called the law “unconstitutional” in a statement and vowed to “challenge it in court.”

TikTok won a legal battle against former President Donald Trump’s attempt in 2020 to force the sale of TikTok via an executive order that would prohibit any U.S.-based transactions with ByteDance if the company did not divest the app within 45 days.
