What I find interesting is that Senator Sessions is speaking out strongly on an issue that helps Trump and no one else. (well, maybe Huckabee or Santorum or some other second tier candidates)
The one thing that warms me to Trump more than anything else is that he seems to have an excellent relationship with Sen. Jeff Sessions, who is probably the most knowledgeable person in the U.S. Senate (including Ted Cruz) on issues of immigration.
