Iowa Senator Tom Harkin advocates the use of unmanned flying drones to patrol the U-S border with Mexico, as opposed to trying to build a fence stretching from the Gulf of Mexico to the Pacific Ocean.
Harkin, a Democrat, says he opposes plans repeatedly being forwarded by Republicans to construct a near-two-thousand-mile-long fence.
Harkin says there are better alternatives to secure and patrol our nation's southern border than a massive fence.
Harkin also says he'd support remote-control surveillance cameras mounted on towers along the border as another alternative.
Fence plans are varied and one estimate of the price tops four-billion dollars.
The director of the F-B-I admitted on Wednesday that the agency has been using drones to patrol both of America's borders -- with Mexico and Canada.
