Washington Redskins v. Steinberg [1]

According to Techdirt [2], a representative of the Washington Redskins football team requested that The Washington Post remove photos from Dan Steinberg's Post-hosted D.C. Sports Bog [3] because of alleged violation of the Redskins' credentialing policy. 

Steinberg published a post about Redskins' fans' discontent with the team and its owner, Dan Snyder.  The post included photographs Steinberg took of fans at a Redskins game, in which the fans displayed their unhappiness with the team in various ways, including by wearing anti-Dan Snyder t-shirts.

The Washington Post removed the photos from Steinberg's blog in response to the request.  According to Cheap Seats Daily [4], the Post removed the photos because it did not want to jeapordize its access to the team.
