( CNN ) -- An investigation into the outing of the CIA 's top intelligence official in Afghanistan last month determined the leak was inadvertent . No one was disciplined or fired , White House spokesman Josh Earnest told reporters Wednesday . When pressed on who was responsible for revealing the name to some 6,000 journalists , Earnest said the White House was focused on changing procedures , rather than one specific misstep . Those new procedures include : . -- Additional training for communications , White House scheduling and advance staff ; . -- On presidential trips abroad , a staffer will notify participants in a meeting open to the press that their names and titles will be released to reporters , giving them an opportunity to object ; . -- On such trips , the White House press lead will clear the names and titles of meeting participants with National Security staff prior to release . The updated procedures are expected to be adopted immediately in the hopes of avoiding another leak . The official 's name was included on a list of people attending a military briefing for President Barack Obama during his surprise visit to Bagram Airfield in Afghanistan last month . It 's common for such lists to be given to the media , but the names of intelligence officials are rarely provided . In this case , the individual 's name was listed next to the title , `` Chief of Station . '' A station chief heads the CIA 's office in a foreign country , establishing a relationship with its host intelligence service and overseeing agency activities . The identities of station chiefs , like most CIA officers , are rarely disclosed to protect them and their ability to operate secretly . Given the potentially dangerous nature of the situation , CNN has not broadcast or published online the name of the official . CNN 's Tom Cohen contributed to this report .
