Everything We Know About The Mole On NCIS: Los Angeles

6/11

A second mole was confirmed.

When Sam's family was threatened in the Season 7 episode "Revenge Deferred," the timeline made it clear that the team was dealing with a second mole who remained active after Carl was stopped.
 
As it happens, the information about Sam's family was leaked to Tahir Khaled (Anslem Richardson), the terrorist network leader and brother of Jada Khaled (Ella Thomas).

Tahir was captured but didn't give up the mole's identity, and he eventually escaped. There was also speculation as to whether Jada would have known how her brother got the information.
