O’Melveny & Myers once again proved its mettle as a litigation machine in 2018, as the firm scored clean wins for top-billing clients in cases that could shape the business industry.

One of those victories came through the firm’s representation of AT&T Inc. and Time Warner, who became mired in a major legal battle with the federal government in November 2017, when the Justice Department brought a historic challenge to their $85 billion merger. It was the first time the government had sought to block a vertical merger in decades, and many had questioned whether President Donald Trump’s well-documented dislike for CNN, Time Warner’s signature news brand, had motivated the lawsuit.
