In 2010, Twitter and the United States Library of Congress partnered together to archive every tweet by American citizens.

The statement is false. While Twitter and the United States Library of Congress did partner in 2010, their collaboration was focused on archiving and preserving significant tweets with historical, cultural, and research value, rather than simply archiving every tweet by American citizens. The partnership aimed to create a comprehensive collection of tweets that would be available for researchers, scholars, and the general public to study and analyze, providing insights into various aspects of society and its evolving communication patterns.
