In 2018, an internal training video surfaced which claimed to provide Amazon employees with "tools for success when it comes to labor organizing." It states that Amazon is "not anti-union, but not neutral either." It provides explicit "warning signs" for "organizing activity" among employees and encouraged against the use of terms such as "living wage". 
In support of Hillary Clinton
Luke Rudkowski tweeted in 2017 that Amazon had deleted all the critical reviews (as measured by the number of stars) of Hillary Clinton's book, What Happened. This lead people to criticise the book but give it 4 or 5 stars.
Udo Ulfkotte's Gekaufte Journalisten
"The English translation of German journalist Udo Ulfkotte’s best-selling book, Gekaufte Journalisten (Bought Journalists) appears to have been suppressed throughout North America and Europe." In April 2018, it was selling for around $1000 a copy. In June 2019, the book had 22 Amazon reviews, all 5/5 stars, and was retailing for around $900.
After a highly publicised publicity campaign throughout 2018 to find a new location to build a second headquarters in the United States, it was reported that Amazon will be developing an HQ2 location in the Crystal City district of Arlington, VA that also encompasses Pentagon City and Potomac Yard in association with developer JBG Smith. Crystal City is located directly south of the Pentagon and includes portions of Pentagon City.
As part of its plan for "National Landing", Amazon has plans to construct several new buildings in Pentagon City and Potomac Yard as well as a pedestrian bridge to the nearby Ronald Reagan International Airport.
