WASHINGTON (Reuters) - Newly retired General David Petraeus was sworn in as CIA director on Tuesday, taking over at a time when the line between the U.S. spy agency and the military has become increasingly blurred in the fight against Islamist militancy.
Petraeus, who in a storied 37-year Army career rose to become arguably the military's brightest star as he worked in Iraq and Afghanistan, took the oath of office from Vice President Joe Biden and then went straight into his first intelligence briefing with President Barack Obama.
