It appears John Morton has tendered his resignation.
From the L.A. Times:
Immigration and Customs Enforcement Director John Morton announced his resignation Monday after more than four years at the head of the agency.
A senior Department of Homeland Security official familiar with the matter said that Morton’s departure was voluntary but acknowledged that the Obama administration was surprised by the timing as Congress is in the middle of debating a comprehensive overhaul of immigration laws.
Morton has been hired as Senior Vice President of Capital One Financial Corp. heading compliance starting this August.
I will always remember him as the man that was "pleased" to report that in a six month period in 2011 his office deported 46,486 parents of United States citizens.
More rats from a sinking ship.
