The Congressional Unmanned Systems Caucus, also informally known as the drone caucus, is a group of members of the U.S. House of Representatives interested in the applications of unmanned vehicle systems, also known as drones (e.g UAVs and UCAVs). The caucus's website states "The Congressional Unmanned Systems Caucus’ goal is to educate members of Congress on every facet of this industry. We are this industry’s voice on Capitol Hill, and will work closely with industry to ensure we continue to expand this sector through efficient government regulation and oversight."[1]
There also appears to be a smaller corresponding group in the U.S. Senate, founded by Sens. Jim Inhofe (R-OK) and Joe Manchin (D-WV).[2]
