A LAW on the books in the District since the mid-1990s gives charter schools first priority to vacated public school buildings. Sadly, that hasn’t prevented city officials from hoarding the properties, selling them off to private interests or, most appalling, letting them rot while deserving charter schools scrounge for space or turn students away. So the decision by Mayor Vincent C. Gray (D) to make more room for the District’s growing charter sector is an encouraging, albeit overdue, step forward.

WHY DIDN’T Congress know earlier that the Internal Revenue Service had targeted conservative groups for special scrutiny? In days of hearings, lawmakers have tried to get a satisfactory answer from witnesses under oath. They haven’t succeeded.

FOUR YEARS almost to the day since outlining a vision of how to fight terrorism, President Obama traveled Thursday to the National Defense University to deliver a self-evaluation, course correction and proposed way forward.

Today we publish a commentary by Senate Minority Leader Mitch McConnell (R-Ky.), arguing against legislation to require expanded campaign finance disclosure. The senator points to the current furor over how the Internal Revenue Service (IRS) mishandled applications from tea party and other conservative groups for tax-exempt status under Section 501(c)(4) of the Internal Revenue Code. We certainly agree with him that the IRS failed to meet basic standards of fairness in selectively pressing the groups for more information and in delaying their applications.
