NEW YORK (AP) - The Justice Department is suing AT&T to stop its $85 billion purchase of Time Warner. That sets the stage for an epic legal battle with AT&T.

The telecom giant's CEO Randall Stephenson said earlier this month that he would not sell "key franchises" of Time Warner to get the deal done.
