Christie veto creates more controversy
Critics of Gov. Chris Christie are accusing him of placing his national aspirations above the interests of his home state.
Christie vetoed a measure that would have banned the use of certain pig cages in New Jersey, which many observers see as a way to appease potential Iowa primary voters.
Animal activists have called the crates cruel since pregnant pigs can't turn around in them.
While the crates are widespread in Iowa, the bill would have had little to impact in the Garden State, since the state's roughly 300 pig farm don't consistently use the crates.
Christie said the bill is a 'solution in search of a problem.'
"It is a political movement masquerading as substantive policy," he said.
He vetoed a similar measure last year.
