Barring a last-minute hiccup, today a Democratic prosecutor — Manhattan District Attorney Alvin Bragg — will begin his unprecedented criminal trial of former President Donald Trump, the Republican Party’s certain presidential nominee in November’s general election.

Despite the obvious political implications of such a prosecution, a new study of ABC, CBS and NBC evening news coverage shows at least 90% of their coverage failed to inform viewers that Bragg and the other elected Democrats going after Trump are “Democrats.” It’s as if the networks prefer to disingenuously portray the indictments and civil lawsuits as the work of nonpartisan career prosecutors, rather than as partisan attempts to use the court system to hobble the electoral prospects of the country’s top Republican.

For this study, our analysts reviewed all broadcast evening news coverage from January 1, 2023 through April 10, 2024. Here’s a rundown of how the networks are failing to adequately disclose the partisanship of the three elected Democrats prosecuting Trump: Manhattan District Attorney Alvin Bragg; Fulton County (Georgia) District Attorney Fani Willis; and New York Attorney General Letitia James.
