Talk about bad timing. Echo Lake Entertainment is set to release its independent film, Truth, the story of former CBS anchor Dan Rather’s self-destruction. It’s based on the 2006 book Truth and Duty: The Press, The President, and the Privilege of Power by Mary Mapes, the discredited CBS producer. Mapes documents and defends Rather’s 2004 attempts to use the forged “Killian documents” to portray former President George W. Bush as someone who shirked duty in Vietnam.
