AT&T Inc. T will face off against the U.S. Department of Justice Monday in a six- to eight-week trial determining the fate of its Time Warner Inc TWX acquisition. Judge Richard Leon announced March 15 that opening arguments will begin Wednesday following two days of hearings. What’s Happened So Far The merger agreement was first announced in October 2016 and quickly drew heat from political powers. President Donald Trump, an outspoken opponent of Time Warner’s CNN, soon denounced the deal. "As an example of the power structure I'm fighting, AT&T is buying Time Warner and thus CNN, a deal we will not approve in my administration because it's too much concentration of power in the hands of too few," Trump said during his election campaign.
