The U.S. Senate has stripped a provision from a key intelligence bill that would have required President Obama to publicly disclose the number of people killed by drone strikes. The move reportedly came at the behest of Director of National Intelligence James Clapper, who suggested it could undermine operations. The provision would have required Obama to report the number of civilians and “combatants” killed or injured in drone strikes, but panel chair Sen. Dianne Feinstein agreed to drop it. Clapper says the Obama administration is exploring its own ways to disclose data on the strikes.
