US President Joe Biden belatedly joined TikTok on February 11, marking his debut on the social media platform with a 26-second video.
The move comes after the US government's sharp criticism of the video-sharing platform in recent years, mostly from Republicans but also from the Biden administration.
TikTok is owned by Chinese firm ByteDance and has been accused by a wide range of US politicians of being a propaganda tool used by Beijing - something the company vehemently denies.
In Sunday's video, posted on the @bidenhq campaign account, the 81-year-old Democratic president light-heartedly touched on topics ranging from politics to the NFL championship game.
Asked if he preferred the Super Bowl or the famous halftime show, which this year was headlined by singer Usher, he chose to watch the game itself.
Asked if there was a secret plot to rig the game so that pop star Taylor Swift - who is dating Kansas City Chiefs star Travis Kelce - could use her fame to support Biden, the president jokingly launched into the baseless right-wing conspiracy theory.
"I'll get myself in trouble if I tell you," he says.
Citing security concerns, a number of individual states and the federal government have banned the app from official government devices.
In Montana, a judge recently blocked a state government move to ban the app altogether.
While the platform continues to be subject to scrutiny by Washington, further federal action to ban or restrict use of the app appears to be off the table.
"It now appears that the idea of a ban was pushed more to score political points than as a serious legislative effort," David Green, a civil rights lawyer, recently told Britain's Guardian newspaper.
As the elections approach, the platform provides an opportunity to connect with young voters. /BGNES
