Good morning, Washington, and welcome to what might be a historic day for the District: the Supreme Court may issue a ruling on the D.C. gun ban. We’ll doubtless have more to say if the ruling comes down, so for now: on to the news!

D.C. Sues CareFirst: WTOP reports that the District is suing the area’s largest health insurance provider, CareFirst. The company is formally a nonprofit, but according to the lawsuit it’s amassed three quarters of a billion dollars’ worth of capital during a period of rising premiums. Councilwoman Mary Cheh is also alleging that executive compensation at CareFirst has grown unreasonably large. The Post’s D.C. Wire blog is also covering the story and speculates that the lawsuit may be payback for CareFirst’s withdrawal from David Catania’s Healthy D.C. initiative.

City To Inspect All Rental Properties: It’s been a tough year for slumlords. The Post ran a series of articles back in March that raised awareness of their shady antics, and since then the city’s been taking steps to resolve DCRA’s failings. Today the paper brings word of the latest such initiative: inspections for every rental property in the city with three or more units. Buildings with a history of problems will be first to be inspected beginning this fall.
