Turner CEO Martin to Testify in AT&T Antitrust Trial

A top Time Warner Inc. executive will testify Wednesday in Washington federal court as the company fights the Justice Department’s antitrust lawsuit seeking to block its sale to AT&T Inc.

John Martin, the chief executive officer of Turner Broadcasting, should be on the witness stand for the most of the day. He’s the first witness in the case from one of the merging companies, rather than an AT&T competitor opposed to the merger.
