Miller, one of many of the sales team for the Iraq war, was a key player in pushing false intelligence that led the public into the Iraq war and was central to the Valerie Plame leak scandal.
As Think Progress notes:
On Sept. 7, 2002, she and fellow New York Times reporter Michael Gordon reported that Iraq had “stepped up its quest for nuclear weapons and has embarked on a worldwide hunt for materials to make an atomic bomb.” As proof, she cited unnamed “American intelligence experts” and unnamed “Bush administration officials.” Subsequently, Condoleezza Rice, Colin Powell, and Donald Rumsfeld all pointed to Miller’s story as justification for war. On April 22, 2003, she told PBS’s Newshour that WMD had already been found in Iraq: “Well, I think they found something more than a ’smoking gun.’”
In 2005, Miller went to jail for refusing to testify in the Valerie Plame scandal and reveal her conversations with Scooter Libby. Miller was often criticized for becoming too close with her Bush administration sources. While she was in jail, for example, Libby wrote to her about how much he admired her and urged her to “Come back to work — and life."
Yep - Miller is nothing if not controversial.
