Two more officials leave DHS

Two more officials leave DHS    The turnover of top officials at the Department of Homeland Security continued Friday with the resignations of Cris Arcos as assistant secretary for international affairs and Chad Boudreaux as Secretary Michael Chertoff’s deputy chief of staff.
   Arcos worked with foreign governments to implement security partnerships with Mexico, Canada, the European Union and other countries.
   Boudreaux played a big role developing immigration policy for the southern border, according to DHS.
   Earlier this month, Tracy Henke announced her resignation as assistant secretary for the Office of Grants and Training.
   The department has also filled several key positions in the past few months, but departures of top officials continue to plague the department and its ability to implement key programs.
