I don’t know if Walker personally ever denied it, some of his operatives did, but the sources for the article at Breitbart stand by the story. It sounds a bit far fetched that someone would make something that specific up out of thin air. It also lines up with speeches that Walker has given on the subject that favored a path to citizenship.
Sometimes his position has seemed rather garbled and hard to understand. What I found surprising is that any serious contender for President would not know and be able to articulate his position on illegal immigration clearly. It is a huge issue to most of us.
They are all selling out the country.
