US President Joe Biden’s re-election campaign has defended its new TikTok account as a vital way to boost its appeal with young voters – even as his administration continued to raise security concerns about whether the popular social media app might be sharing user data with China’s government.

The campaign’s first post featured the president being quizzed on Sunday’s Super Bowl and included a reference to the latest political conspiracy theory involving pop superstar Taylor Swift.
