A proposal to send National Guard troops to the U.S.-Mexico border to counter drug trafficking has triggered a bureaucratic standoff between the Pentagon and Department of Homeland Security over the military’s role in domestic affairs, according to officials in both departments.

Gates, in what their subordinates describe as a turf fight over who should direct the use of troops to assist in the fight against Mexican cartels and who should pay for them.
