Did you even read the actual NYT article? I'm guessing not, because I'm sure you would've spotted this:
"The Times examined and analyzed the data from thousands of individual and business tax returns for 2000 through 2017, along with additional tax information from other years. The trove included years of employee compensation information and records of cash payments between the president and his businesses, as well as information about ongoing federal audits of his taxes. This article also draws upon dozens of interviews and previously unreported material from other sources, both public and confidential. All of the information The Times obtained was provided by sources with legal access to it."
Also, in terms of the NYT, it has no bearing on *how* its sources obtained the data. The NYT and its reporters are only criminally liable if they directly took part in the theft of the data -- see the Julian Assange charges related to Chelsea Manning for more on that scenario. And even then, the legality of prosecuting journalists for assisting sources in that way is still being debated. But there's no indication that the Times reporters were involved in the acquisition or extra-legal theft of the tax data. And you can't charge journalists with reporting classified or confidential information EVEN IF IT WAS OBTAINED ILLEGALLY BY SOURCES (see Snowden and the Guardian, Washington Post, etc.).
P.S. Who the fuck are Viva Frie and Robert Barnes, and why are you investing anything in what they say on this matter when they can't get one of the most basic facts right?
