He's a joke. He should be a little more responsible for improving the condition of Mexico so that all of its people don't want to leave.
There is no job on earth that U.S. citizens will not do, (or have not done),
for a fair, competitive wage. There are also millions of people in 3rd world countries across the globe who would give anything to have the opportunity to work here and send cash home, but they cannot sneak over in the trunk of a car from India or Africa. Legal immigration would be a lot more fair.
