Republican leaders renewed their attacks on the Obama administration over suspected leaks of classified security information Sunday. Recent press reports including stories in Newsweek and The New York Times detailed the administration’s drone-warfare program, among other elements of Obama’s national-security strategy. “Our intelligence people say this is the worst breach they’ve ever seen,” Sen. John McCain said on CNN on Sunday. “It’s very clear that this information had to come from this administration. It couldn’t have come from anywhere else.” While Attorney General Eric Holder has appointed two federal prosecutors to look into the leaks, McCain called for a “special counsel” independent of the Department of Justice to be given the task.
