According to ChainCatcher, US Vice President Harris recently joined TikTok (the overseas version of Douyin) and posted videos to attract young voters. She has posted four videos so far and has about 3 million followers. Analysts say this may play a key role in boosting Harris's early campaign. In March this year, Harris said: "We have national security concerns about the owner of TikTok, but we have no intention of banning TikTok."

Previously reported, the ABC poll showed that Harris's approval rating rose to 43% today.
