Secret Service Director Ronald Rowe testified that an "autonomous robot" was being used to protect President-elect Donald Trump.
Rowe made the remarks Thursday during a hearing with a House task force investigating the attempted assassinations of Trump.
The Secret Service director said his agency had worked with the Department of Homeland Security's Science and Technology Directorate to utilize the new capabilities.
"What I'm trying to do is put the secret back in the Secret Service, but there's been media coverage of this, so I'll talk about it," Rowe said. "Right now at Mar-a-Lago, we've started using a sensor array, an autonomous robot that's out there walking the seawall right now."

"Those are the types of technologies that have been out there, that have been in DOD world for years," he added. "The use of the autonomous canines down there right now is just one example of that."
In November, the robot dog was first spotted patrolling at Mar-a-Lago.
