Defense attorneys for a Chicago businessman charged in the deadly 2008 Mumbai attacks say the government's star witness is a "lifelong manipulator."
Attorneys for Tahawwur Rana say their client had no knowledge of the plot on India's largest city and a separate plot that was never carried out in Denmark.
In closing arguments on Tuesday, defense attorney Patrick Blegen says if Rana knew about the Mumbai plot he would not have traveled to the city with his wife during the same month to look after a branch of his immigration business that was located there.
Rana is accused of providing cover for his longtime friend and admitted terrorist David Coleman Headley, who has pleaded guilty to laying the groundwork for the attacks. Rana has pleaded not guilty.
