They are fools and once Trump wins in November, they could be in serious trouble. The NYT is in possession of the stolen federal property which is a felony. In addition to this, many other laws apply. For instance, this one:
26 U.S. Code § 7213 – Unauthorized disclosure of information
(a)Returns and return information
(1)Federal employees and other persons
It shall be unlawful for any officer or employee of the United States or any person described in section 6103(n) (or an officer or employee of any such person), or any former officer or employee, willfully to disclose to any person, except as authorized in this title, any return or return information (as defined in section 6103(b)). Any violation of this paragraph shall be a felony punishable upon conviction by a fine in any amount not exceeding $5,000, or imprisonment of not more than 5 years, or both, together with the costs of prosecution, and if such offense is committed by any officer or employee of the United States, he shall, in addition to any other punishment, be dismissed from office or discharged from employment upon conviction for such offense.
(This is just one law. There are many others.)
