That decision was made despite direction from her boss - President Obama - that administration officials should use official email accounts. It also came despite his - and her - promises of improved government transparency. And despite her 2007 criticism of Bush administration use of "secret White House email accounts."
Why didn't someone on her team push back, and insist Secretary Clinton reconsider?
Flashback to January 1996. Writing in The New York Times, reporter David Johnston wrote of Mrs. Clinton's secretive role in the firings of White House travel office staffers and, significantly, "a climate of fear in which officials did not dare question Mrs. Clinton's wishes."
What is past is prologue.
Then, and now, Clinton loyalists describe shortcuts taken on her behalf as inadvertent and innocent. For convenience, they say, not protection. Clinton critics, then and now, see cutthroat use of power and a trademark penchant for control and secrecy.
Her camp's response to the email controversy so far is textbook Clinton crisis management: say -- and do -- as little as possible, just enough to keep inevitable controversy from ballooning into unpredictable crisis.
