An hour after expanding on a bipartisan immigration proposal on Monday, Sen. John McCain (R-AZ) called for an increase in security technology at the U.S.-Mexico border, including unmanned drones in a Fox News interview.

"We have to use a lot of high-tech — we've got to use drones," McCain told "Your World with Caputo" guest host Eric Bolling. "We've got to do a lot of things to get that border secure, but that must be done."

According to The Hill, the plan, crafted by McCain and seven other U.S. senators, calls for border security standards to be set by a group of officials from border states, who would have the ability to stall a path to citizenship for undocumented immigrants if they are not satisfied by security efforts.

The extra technology, McCain said, would also help protect U.S. personnel.

"One of the big problems, as you know, on the southwest border is, you know, it gets so unbearably hot in the summer," he told Bolling. "It's very difficult for our men and women who are doing such a great job to perform very efficiently."

A study released last year found that immigration from Mexico to the U.S. had reached "net zero" -- more Mexicans were leaving the country than coming in. That didn't stop Bolling from expressing concern over the group's wishes to moving as quickly as possible with whatever legislation emerges from the increased political movement on the issue.

If a bill made it past Congress and was signed by President Barack Obama quickly, Bolling asked, "Won't we have a flood of illegals coming across the border trying to beat the time, beat the clock, saying, 'I have to get there, because if I just get there, I'll be able to stay.'"

"I'm sure we can set a date that anybody who comes afterwards would not be eligible," McCain said. "I'm sure we will."
