"Stephen Yale-Loehr, a professor of immigration law at Cornell Law School, says that the executive branch has wider prosecutorial discretion than the White House is letting on. The problem, he argues, isn’t that Obama can’t stop deportations. It’s the simple fact that doing so is a political risk, and one the president doesn’t want to take. “He has wide legal authority, but you have to balance that against the will of the people and politically what you can get through Congress if you push your executive authority too far,” Yale-Loehr says." - U.S. News & World Report, Feb. 25, 2014.
