Career employees at the General Services Administration, which provides administrative and technological support for much of the federal bureaucracy and manages the government’s real estate portfolio, were responsible for the oversharing, which spurred a cybersecurity incident report and investigation last week. 

The records show that the employees inadvertently shared a Google Drive folder containing the sensitive documents with the entire GSA staff, which totals more than 11,200 people, according to the agency’s online directory.

The information shared also included the details of a proposed blast door for the White House visitor center, the records show, as well as bank account information for a vendor who assisted with a Trump administration news conference.

The incident is the latest digital security lapse for the Trump administration. Last month, top officials inadvertently included the editor-in-chief of the Atlantic magazine in an unclassified chat used to discuss highly sensitive military planning, and Trump’s national security adviser and his staff used personal Gmail accounts for government communications, which experts described as insufficiently secure, The Post reported.
