( CNN ) -- A proposed Arizona law would deny birth certificates to children born in the United States to illegal immigrant parents . The bill comes on the heels of Arizona passing the nation 's toughest immigration law . John Kavanagh , a Republican state representative from Arizona who supports the proposed law aimed at so-called `` anchor babies , '' said that the concept does not conflict with the U.S. Constitution . `` If you go back to the original intent of the drafters ... it was never intended to bestow citizenship upon ( illegal ) aliens , '' said Kavanagh , who also supported Senate Bill 1070 -- the law that gave Arizona authorities expanded immigration enforcement powers . Under federal law , children born in the United States are automatically granted citizenship , regardless of their parents ' residency status . iReporter supports the bill . Kyrsten Sinema , a Democratic state representative , strongly opposes the bill . `` Unlike ( Senate Bill ) 1070 , it is clear this bill runs immediately afoul of the U.S. Constitution , '' she said . `` While I understand that folks in Arizona and across the country support S.B . 1070 , they do so because we have seen no action from the federal government , '' said Sinema . `` Unfortunately , the so-called 'anchor baby ' bill does nothing to solve the real problems we are facing in Arizona .
