Rep. Steve King (R-Iowa), arguably the chief GOP opponent of immigration reform in the House, said Thursday that some Republicans have been under a spell on the issue since the 2012 election.

"Last year, almost everybody in my conference would have agreed with me on this immigration issue,” King told CNN's "New Day." "And this year, it seems as though after the presidential election, a spell’s been cast over a good number of Republicans, and they seem to think the presidential election was about immigration."
