Just to make things clear, Obama deported more illegals than Trump because he could. We can only immediately send illegal aliens back to their own country if they are from Mexico or Canada. We haven't been able to send illegals back to such countries as El Salvador, Guatemala and Honduras because of that loophole. The vast majority of border crossings are now from countries other than Mexico. That ratio was much different during Obama's presidency and thus deportations were more numerous because the amount of illegal aliens being caught at the border were slanted more heavily in Mexico's favor. We are now receiving a much higher proportion of Central Americans and others that are not Mexican and are presently prohibited from immediately deporting them, but must keep them here in country until their court hearings.
