As reported by engadget,
As soon as President Donald Trump assumed office in January 2017, Twitter archived tweets from the Obama administration on @POTUS with a new account, @POTUS44. That account retained all of its followers, and Twitter also added all of those followers to the Trump administration’s fresh @POTUS account. That won’t be the case this time around.
In 2020, Twitter has informed us that as of right now the Biden administration will have to start from zero. https://t.co/wj1R02SmiK

Rob Flaherty, a digital director for Biden, wrote (on Twitter, naturally) that the company won’t transfer the followers from the accounts in question. He told Bloomberg that although the Biden team pushed back on that decision, the company stood firm. A Twitter spokesperson told the publication it’s working with the transition team on a number of matters related to White House accounts.
Trump doesn’t actually tweet from the POTUS account often. Instead, it typically retweets posts from his own account, which has more than 88.5 million followers. Meanwhile, Trump’s personal activity on Twitter, which has caused controversy on many occasions, will be held to different standards once he leaves office.
