The AP reports:
The State Department’s security chief announced his resignation on Wednesday in the wake of last month’s deadly Blackwater USA shooting incident in Baghdad and growing questions about the use of private contractors in Iraq.
Richard Griffin, the assistant secretary of state for diplomatic security, announced his decision to resign at a weekly staff meeting, according to an internal informational e-mail sent to colleagues.
“He read his letter of resignation at the weekly Diplomatic Security staff meeting,” said the e-mail, which was read to The Associated Press by one its recipients. “There was no detailed reason provided and no effective date identified at this time.” …
Griffin announced his resignation just a day after Rice ordered a series of measures to boost government oversight of the private guards the department uses to protect its diplomats in Iraq.
