From examiner.com:

Recently, Rep. Steve King drew the ire of Democrats and many open-borders Republicans alike, for characterizing many young illegal aliens as drug mules.

For everyone who’s a valedictorian, there’s another 100 out there that weigh 130 pounds and they’ve got calves the size of cantaloupes because they’re hauling 75 pounds of marijuana across the desert.

Of course, King’s comments, tough not politically-correct, were based on fact…

For decades, the business of smuggling Mexican nationals into this country illegally was led by local ‘coyotes.’ These men lived in the same region or village as those planning to make the illegal journey, and the cost was relatively low.
