Since Republican front-runner Donald Trump included ending the practice in his immigration platform released Sunday, the issue has split the GOP field. Sen. Lindsey Graham (R-SC), Gov. Bobby Jindal (R-LA), Gov. Scott Walker (R-WI) and Gov. Chris Christie (R-NJ) have all suggested they would be open to changing the practice, and Sen. Rand Paul (R-KY) co-sponsored a bill in 2011 to limit birthright citizenship. Meanwhile former Florida Gov. Jeb Bush, former Arkansas Gov. Mike Huckabee, Sen. Marco Rubio (R-FL) and former Hewlett-Packard CEO Carly Fiorina have rejected the idea.
Most legal experts say ending birthright citizenship would require a constitutional amendment. However some supporters of changing the policy, like Rep. Steve King (R-IA), say it would only require a federal statute.
