Potential 2016 candidate Scott Walkers staff is denying that he endorsed amnesty for illegal immigrants during a closed-door dinner with Republican donors in New Hampshire.Governor Walker has been very clear that he does not support amnesty and believes that border security must be established and the rule of law must be followed, said Kirsten Kukowski, the spokesman he recently hired from the Republican National Committee.He does not support citizenship for illegal immigrants, and this story line is false, she said.
