President Joe Biden’s campaign has joined TikTok, despite the app being banned on most US government devices over security concerns.
His campaign launched its account with the username “@bidenhq” during the Super Bowl on Sunday.
In a launch video, captioned “lol hey guys”, aides quizzed Mr Biden about his preferences for the big game.
The president signed legislation in 2022 blocking most federal government devices from using TikTok.
Several states have also adopted the measure. Lawmakers from both sides of the aisle have called for the app - owned by Chinese company ByteDance - to be banned in the US over concerns the government in Beijing might be able to access user data.
Still, the site remains popular with young people in the US, a demographic that helped boost Mr Biden to victory in the last election.
His TikTok account will not be run by the president himself, but by his campaign team, aides told US media.
Asked in the launch video if he was rooting for the Kansas City Chiefs or the San Francisco 49ers, Mr Biden said the Philadelphia Eagles, because otherwise “I’d be sleeping alone” as “my wife’s a Philly girl”.
He was also asked about a Taylor Swift Super Bowl conspiracy theory that saw some claim the singer’s relationship with Kansas City Chiefs star Travis Kelce was part of a plot to rig the NFL’s championship game and help get Mr Biden re-elected this November.
“I’d get in trouble if I told you” about the conspiracy, Mr Biden joked.
Mr Biden faced a stumbling block in his re-election campaign last week after a justice department inquiry into his handling of classified documents called him a “well-meaning, elderly man with a poor memory”.
Special counsel Robert Hur did not recommend charges for Mr Biden.
“How can I reach younger voters while doing absolutely nothing of substance for them?”
