After some setbacks over the past several weeks, top aides to Wisconsin Gov. Scott Walker tell Breitbart News that he’s toughening up his immigration position as he learns more about the issue. “He’s for border security first, enforce the laws on the books, fix legal immigration system with national interest in mind and then deal with those here,” Walker spokeswoman Kirsten Kukowski said in an email. Kukowski’s comments to Breitbart News come after a trip Walker took on Friday to the border with Republican Texas Gov. Greg Abbott. A lot depends on what the governor means by a: “legal immigration system with national interest in mind.” Still, this could be a step toward Walker remaking his image on immigration in the manner of Senate Judiciary Committee subcommittee on Immigration and the National Interest chairman Sen. Jeff Sessions (R-AL).
