Kristen Welker informed viewers of the NBC Nightly News that an "undocumented worker" was at fault in a terrible bus crash in Louisiana on August 28 that killed two people and injured 41 others. It is typical of the media to use that phrase when referring to illegal aliens. It is how the media try to condition people to accept their presence in the United States. After all, if these people are "workers," they can't be such terrible people. On the other hand, the word "alien" implies something foreign to the United States.
The Breitbart website, under fire from the liberal media and Hillary Clinton, was accurate, noting that "illegal alien" Denis Yasmir Amaya Rodriguez drove the private rental bus that crashed into a fire truck, two other vehicles and three firefighters.
