The Department of Homeland Security this week left several key logistical questions unanswered related to how it will implement President Trump’s Wednesday executive order aimed at stopping illegal immigrant families from being separated.

DHS headquarters and agency spokesmen went silent Thursday as the department’s leadership grappled with how to implement a plan it helped the White House write a day earlier. One department official who asked to remain anonymous acknowledged to the Washington Examiner Thursday night there was little being said publicly about how it would go about implementing the change because press officers department-wide were told not to speak with reporters.
