A former Secret Service agent who used to work at the White House said that the agency’s leadership needs to “broaden its mind” and bring in new perspectives to prevent “complacency.” "When you say complacency, it means when you get used to nothing ever happening typically, when something does happen you fail to connect those dots properly,'' former agent Evy Poumpouras said on “Today.” Poumpouras spoke out after a Washington Post report that said it took four days for the Secret Service to realize a gunman had hit the White House in 2011.
