An FBI interpreter with top clearance traveled to Syria and married the ISIS terrorist she had been assigned to investigate. In an exclusive report, CNN News unravels the strange case of FBI interpreter Daniela Greene, 38, who went to Syria in 2014 and married the brutal terrorist who had appeared in ISIS propaganda videos holding human heads.
He was considered one of the most violent operatives in Syria, including singing songs of praise to Osama bin Laden, threatening Barack Obama with a throat cutting gesture, and holding a bloody head in a recruiting video.
Within weeks of their marriage, Greene, born in Czechoslovakia and raised in Germany, realized marrying Cuspert was a mistake and fled back to the US, where she was arrested and eventually served two years in prison.
'It's a stunning embarrassment for the FBI, no doubt about it,' John Kirby, a former State Department official, told CNN.
