Obama to hand over social media accounts to new president
[...] all the material published online during Obama's presidency will be preserved with the National Archives and Records Administration, just as previous administrations have done with handwritten notes, faxes and emails.
[...] materials will continue to be accessible on the platforms where they were created, allowing for real-time access.
[...] the White House is working to ensure the next president can continue to use and develop the digital assets the Obama administration has created to connect directly with the people they serve.
