Senate Minority Whip Jon Kyl (R-Ariz.) warned Sunday that the repeal of the "Don't ask, don't tell" law, passed with the help of eight Republicans on Saturday, could disrupt the efficiency of small combat units and potentially cost lives.

Kyl said that the military "has one function: to fight and to fight well" — and potentially give their lives in the process.
"When it comes especially to the small units that do the fighting on the ground ... [the repeal] could disrupt unit cohesion ... and cost lives," he said.
