Unless he has provided specific details about identifying the aliens, terminating welfare/support benefits and effectively transporting them back to their native countries, he could only have made "quite clear" his very broad campaign promise to do so, not their return.
Has he specifically declared he will deport the tens of thousands of Cuban aliens?
Last night's reiteration of his immigration policy seemed clear: Cruz would use e-verify to deny illegals jobs and he would cut off non-citizen access to welfare payments.
At which point, the illegal is left with little choice other than to self-deport.
