Time Warner’s chief legal officer berated and made threatening gestures and remarks toward U.S. Department of Justice lawyers during a November 2017 meeting over the media company’s proposed merger with AT&T, according to declarations filed with the U.S. District Court for the District of Columbia.

The government lawyers’ claim was contradicted, however, in a declaration from William Barr, a Time Warner board member who served in the 1990s as U.S. attorney general.
