Editor's Notes
- While I expected online blogs and maybe some smaller papers to use the quote, I did not think it would have a major impact. I was wrong. Quality newspapers in England, India, America and as far away as Australia had my words in their reports of Jarre’s death. I was shocked that highly respected newspapers would use material from Wikipedia without first sourcing and referencing it properly.
- On July 19, 2010, Shirley Sherrod was forced to resign from her position as Georgia State Director of Rural Development for the United States Department of Agriculture [1] after conservative blogger Andrew Breitbart posted video excerpts of Sherrod's address at a March 2010 NAACP event to his website. [2] The NAACP condemned her remarks, and U.S. government officials called on her to resign. However, upon review of the unedited video in context, the NAACP, White House officials, and Tom Vilsack , the Secretary of Agriculture , apologized and Sherrod was offered a new position. The first news outlet to report on the Breitbart video was FoxNews.com , which posted an article about the story on its website. [16] [14] The New York City affiliate for CBS also posted a report on its website later that afternoon. [14] The Atlanta Journal Constitution newspaper's related website also soon picked up the story. [17] In addition, the story was picked up and reported widely in the blogosph A ccording to Sherrod, that afternoon she received numerous demands from government officials to submit her resignation, demands that she characterized as harrassment. [18] In response to a call from USDA deputy undersecretary Cheryl Cook, Sherrod submitted her resignation via email. Sherrod claims that Cook told her White House officials wanted her to quit immediately because the controversy was "going to be on Glenn Beck tonight [18] ", a claim disputed by White House Press Secretary Robert Gibbs.
