A senior official at the Department of Justice submitted his resignation after being ordered by the Trump administration to target sanctuary cities. 

Corey Amundson spent more than two decades at the DOJ, rising to become the head of the department’s public integrity section. After the Trump administration came into power last week, he was directed to sit on the newly created Sanctuary Cities Enforcement Working Group, a task force focused on taking legal action against sanctuary cities. Amundson was one of an estimated 20 senior career DOJ attorneys who were going to be reassigned by the new White House.
