The director of US Immigration and Customs Enforcement will resign at the end of July. John Morton was appointed by president Obama in 2009, and unanimously confirmed by the US Senate. He's the third and longest serving director in the agency's history. During Morton's tenure, ICE agents began to focus deportations on undocumented immigrants with serious criminal backgrounds and those who posed a national security risk. At the same time, deportations under the Obama administration rose at a record pace, topping 400-thousand in 2012. Morton will be joining a financial services company when he departs government service.
