In April 2012, Brennan was the first Obama administration official to publicly acknowledge CIA drone strikes in Pakistan, Yemen, Somalia, Libya, Afghanistan, and elsewhere. In his speech, he explained the legality, morality, and effectiveness of the program. The ACLU and other organizations disagreed. In 2011–2012, he also helped reorganize the process, under the aegis of the Disposition Matrix database, by which people outside of war zones were put on the list of drone targets. According to an "Associated Press" story, the reorganization helped "concentrate power" over the process inside the White House administration. According to "The New York Times", Brennan was the "principal coordinator" of U.S. kill lists. Former Obama administration counter-terrorism official Daniel Benjamin has stated that Brennan "probably had more power and influence than anyone in a comparable position in the last 20 years".
