Following a Memorial Day break, testimony resumes Tuesday in the high-profile trial of a Chicago business man accused in the 2008 Mumbai, India, terrorist attacks.

Prosecution star witness David Headley is returning to the witness stand Tuesday to face questions from defense attorneys for suspect Tahawwur Rana.

Rana is accused of helping Headley lay the groundwork for the Mumbai attacks that left more than 160 people dead.

Headley has already pleaded guilty and agreed to testify against Rana.
