By David Shepardson and Diane Bartz WASHINGTON (Reuters) – AT&T Inc's planned $85.4 billion acquisition of Time Warner Inc will increase innovation and bring “better-priced options” to consumers upset by high cable bills, AT&T Chief Executive Randall Stephenson told lawmakers on Wednesday. “We want consumers to pay for their content once and watch it any where any time,” he said at a hearing of the Judiciary Committee's antitrust panel. Senator Amy Klobuchar, the ranking Democrat on the panel, expressed concern that the deal would create incentives for AT&T to refuse to license Time Warner's movies and television shows to competitors.
