Communications Over Various Feeds Electronically For Engagement Act of 2017” or the “COVFEFE Act of 2017”

This bill amends provisions governing presidential records to: (1) revise the definition of "documentary material" to include social media; (2) revise the definition of "presidential records" to include any personal and official social media account; and (3) define "social media" as any form of electronic communication (such as a website for social networking and microblogging) through which users create an online community to share information, ideas, personal messages, and other content (such as videos).

By shutting down POTUS social media, they’re making official presidential records inaccessible to the public.
