 In 2013, the sustained and growing criticism of his drone policy forced Obama to announce stricter conditions on executing drone strikes abroad, including an unspoken plan to partly shift the program from the CIA to the ostensibly more accountable Pentagon, In anticipation of his speech, Obama instructed Attorney General Eric Holder to divulge that four U.S. citizens had been killed by drones since 2009, and that only one of those men had been intentionally targeted.Following Obama's announcement, the United Nations' drone investigator, British lawyer Ben Emmerson, made clear his expectation of a "significant reduction" in the number of strikes over the 18 months to follow, although the period immediately after Obama's speech was "business as usual".Six months later, the CIA was still carrying out the "vast majority" of drone strikes.
