Chertoff loses chief of staff

Chertoff loses chief of staff    The churn of mid and high-level officials at the U.S. Department of Homeland Security continued this week with the announcement that John Wood, Secretary Michael Chertoff’s chief of staff, had resigned, effective immediately.
   Wood began his DHS stint in February 2005 when Chertoff took office.
   Last month Chad Boudreaux, the deputy chief of staff, left the department.
   The constant departure of experienced officials has contributed to the department’s failure to meet deadlines, move programs forward on schedule and develop new security strategies, according to political observers in Washington.
