Outgoing president Donald Trump was an obsessive Twitter user from his personal account — which was banned by the platform over his incitements to violence — while also using the official accounts associated with the presidency.

“There is no time to waste when it comes to tackling the crises we face,” Biden said in a tweet at @POTUS.

“That’s why today, I am heading to the Oval Office to get right to work delivering bold action and immediate relief for American families.”

A message tweeted from the @VP account, Harris tweeted “Ready to serve” from her @VP account.

In his @SecondGentleman profile, Douglas Emhoff described himself as a proud husband.

Biden’s team also inherited the official @WhiteHouse, @PressSec, and @FLOTUS accounts.

After the unprecedented violence in the seat of Congress, Trump was banned for inciting the rioters — on platforms including Facebook, Twitter, Google-owned YouTube, and Snapchat.
