Drop fliers telling the caravan that if they get into the US they will get no food. housing or medical. If we keep them off of every government program they will leave. Tell them the only money they get from us is a plane ticket home.
Also tell Mexico if the caravan keeps coming we will stop all money coming from the US to Mexico. Since it is the 2nd largest part of their economy they cant do without it.
