London (CNN Business) A new report about the close relationship between Fox News and President Donald Trump says the President personally asked a top White House aide to make sure the Justice Department stopped AT&T from purchasing Time Warner.

Ever since the Justice Department sued in 2017 to block AT&T's acquisition of Time Warner, theories and accusations of political animus has swirled around the antitrust case.

At the heart of the theories is Trump's public dislike of CNN, which was a division of Time Warner. The company that has since been renamed WarnerMedia, which also includes networks such TNT and HBO, in addition to CNN.

In a new piece for the New Yorker , investigative journalist Jane Mayer reports that a few months before the Justice Department filed its lawsuit, Trump pressured Gary Cohn, the former director of the National Economic Council, to tell the Justice Department to block AT&T's Time Warner deal.

According to Mayer's source, Trump called Cohn and then Chief-of-Staff John Kelly into his office and said to Kelly, "I've been telling Cohn to get this lawsuit filed and nothing's happened! I've mentioned it fifty times. And nothing's happened. I want to make sure it's filed. I want that deal blocked."
