You just reminded me of this!
Covfefe Act!
Did twitter just violate this law of preserving Presidential tweets?
(Wikipedia quick description)
https://en.wikipedia.org/wiki/COVFEFE_Act
The Communications Over Various Feeds Electronically for Engagement Act (COVFEFE Act) is a bill introduced by the United States House of Representatives on June 12, 2017, during the 115th United States Congress.
The bill amends the Presidential Records Act to preserve Twitter posts and other social media interactions of the President of the United States, and to require the National Archives to store such items.
