Justice Department subpoenas New York Times reporters over Air Force One reporting

The New York Times says several of its journalists have been subpoenaed by the Department of Justice over their reporting on Air Force One, describing it as a "brazen act."

On Wednesday, the newspaper published an anonymously sourced story that the Secret Service urged President Trump to leave the recent NATO summit in Turkey on an older version of Air Force One instead of the Boeing 747 donated by Qatar last year because of security concerns. The following day, the Times reported, again citing anonymous sources, that the gifted plane lacked "defensive countermeasures that were security features of the old model, including its advanced antimissile capabilities."

The four reporters bylined on Wednesday's article -- Julian E. Barnes, Eric Lipton, Tyler Pager and Eric Schmitt -- all received subpoenas, according to the Times. The paper said federal agents delivered the subpoenas Friday evening to some reporters at their homes.

The subpoenas "seek to force the reporters to testify before a federal grand jury in Manhattan on Wednesday," the Times reported. Their testimony, according to the subpoenas, was requested "in regard to an alleged violation of federal criminal law."

"The appearance of Federal law enforcement agents on the doorstep of news reporters should shock the conscience of any American who believes in the Constitution and the press freedom it protects," David McCraw, senior vice president and deputy general counsel for the Times, said in a statement. "Our journalists report the facts and advance the American public's right to know how their government is operating and their taxpayer dollars are being used. This brazen act should be seen as nothing more than an attempt to prevent the public from knowing what is happening in their country by intimidating journalists from doing their jobs."

Before the Times published the Wednesday article, a senior FBI official had contacted a reporter and editor and asked that the story be held, without explaining why, a New York Times spokesman tells NPR. The FBI official also asked that the sources for the story be identified. Both Times employees refused to do either.

The subpoenas were issued by U.S. Attorney Jay Clayton of the Southern District of New York, who was recently nominated by Trump to be the next national intelligence director.

The president of the Reporters Committee for Freedom of the Press, Bruce D. Brown, said in a statement Saturday, "The subpoenas issued to journalists at The New York Times break from longstanding Justice Department practice to protect the public interest and press independence by requiring prosecutors to only seek information from reporters as a last resort when all other avenues have been exhausted."

The move to subpoena the Times journalists is the latest escalation in Trump's years-long effort to cow and control U.S. media outlets, following previous financial settlements with ABC News and CBS News' 60 Minutes program, alongside civil lawsuits and federal criminal actions taken against The Wall Street Journal, The Washington Post, the BBC and others since he resumed office last year.
