Palin v. Moore [1]

On July 4, 2009, an attorney for Alaska Governor Sarah Palin sent an open letter [2] to Alaska blogger Shannyn Moore [3], the Huffington Post, MSNBC, the New York Times, The Washington Post, and other news organizations threatening to file defamation lawsuits if they claimed "as 'fact' that Governor Palin resigned because she is 'under federal investigation' for embezzlement or other criminal wrongdoing." 

Attorney Thomas Van Flein states in the letter [2]:

To the extent several websites, most notably liberal Alaska blogger Shannyn Moore, are now claiming as "fact" that Governor Palin resigned because she is "under federal investigation" for embezzlement or other criminal wrongdoing, we will be exploring legal options this week to address such defamation. This is to provide notice to Ms. Moore, and those who re-publish the defamation, such as Huffington Post, MSNBC, the New York Times and The Washington Post, that the Palins will not allow them to propagate defamatory material without answering to this in a court of law. 

According to Politico [4], neither the New York Times nor The Washington Post "made any mention of the embezzlement rumors in their Saturday editions, but sources close to Palin consider the letter a warning shot to stay away from the topic."
