John McLaughlin, who took temporary command of the CIA for three months this year during a wave of criticism of the spy agency, is retiring amid internal conflicts.

In a statement, McLaughlin, the CIA's deputy director and 32-year agency veteran, called his departure a "purely personal decision" and said it was time to move on to other endeavors.

Goss, a Florida Republican who formerly chaired the House Intelligence Committee, brought four of his congressional aides with him to the CIA's 7th floor executive offices shortly after he took over in September.
