President Joe Biden's administration buying drones from a Chinese company is "harmful to our national security," former Director of National Intelligence John Ratcliffe says.

Records made public in September show that the Secret Service bought drones from Da Jiang Innovations (DJI) in July. That purchase came just a few days after the FBI purchased drones from the Chinese company.

About a month before the purchases, the Biden administration's End-User Review Committee revised (pdf) the designation for DJI, excluding some of its technology from the department's entity list.

The list "identifies entities for which there is reasonable cause to believe, based on specific and articulable facts, that the entities have been involved, are involved, or pose a significant risk of being or becoming involved in activities contrary to the national security or foreign policy interests of the United States."
