Trump administration subpoenas New York Times journalists over Air Force One reporting

Several New York Times journalists were summoned to testify under oath after they reported alleged security concerns involving President Donald Trump's new Air Force One plane, the US newspaper said.

The Times reported on Wednesday that while Trump flew to the Nato summit in Turkey on the new Air Force One, he left the summit on an older plane on the advice of the Secret Service.

A former US government official told CBS that there was not enough time or money for the plane to be updated with the security requirements to serve as Air Force One.
