WASHINGTON (AP) - The fate of the AT&T-Time Warner merger, a massive media deal opposed by the government that could shape how much consumers pay for streaming TV and movies, rests in the hands of a federal judge.

U.S. District Judge Richard Leon is expected to announce in court Tuesday his decision in the biggest antitrust trial in years. The Trump Justice Department sued to block the $85 billion merger, arguing that it would hurt competition in pay TV and cost consumers more to stream TV and movies.

The mega-merger is a high-stakes bet by AT&T Inc. on the synergy between companies that produce news and entertainment and those that funnel it to consumers - who spend more time watching video on phones and tablets and less time on traditional live TV on a big screen.
