From ABC News: CIA Chief in Pakistan Exits; Led OBL Hunt Team
The CIA station chief who oversaw the intelligence team that found Osama Bin Laden has left Pakistan for medical reasons and is not returning, the second time the agency’s most senior officer in Pakistan has left in the last seven months, according to US and Pakistani officials.
The Islamabad station chief -- one of the agency’s most-important positions in the world -- arrived only late last year after his predecessor was essentially run out of town when a Pakistani official admitted his name had been leaked. The departure of two station chiefs in such a short amount of time threatens to upset a vital intelligence office. US officials, however, insisted that the quick turnover would not harm US intelligence efforts in Pakistan.
