Jeb Bush released a six-point outline Monday of his plan to secure the U.S.’s southern border to stop the flow of illegal immigration.

In a post written on Medium, Bush said he would station patrols at the border on shifts that last multiple days, enabling them to be more flexible in responding to threats; use new technology, such as drones, radar and sensors, to detect illegal crossings; and bolster the construction of roads and infrastructure so patrolmen can better traverse the difficult terrain.
