I was surprised to hear on the radio that the DOD was lobbying in support of the immigration bill. Now I know why. Apparently, the army is having trouble reaching their target recruitment numbers, so they have great deal of interest in the Development, Relief and Education for Alien Minors (DREAM) provision that allows illegal aliens to join the military.
An interesting outcome of this is that under a Bush executive order that allows non-citizen enlistees to apply for citizenship within one day of service these illegals would be granted amnesty and a quick path to citizenship.
Read the press release from the DOD.
