The Los Angeles Times' David G. Savage reports that President Obama's use of executive action to shield immigrants from deportation won't just raise the ire of Congressional Republicans: "By claiming the power to forge ahead based on his executive authority, the president may well lose the one conservative he still really needs: Chief Justice John G. Roberts Jr." Savage wonders if Obama's immigration action could influence how Roberts views the latest challenge to the Affordable Care Act: "At issue is whether the administration must abide by one provision in the healthcare law, which says subsidies may be paid to those who enrolled in state health exchanges, or whether the president can extend those benefits to include people who signed up on the federally run exchange."
