"If you passed the strongest gun-control legislation tomorrow, I don't think it will have a profound effect on the tragedies we have seen," he told Vermont alternative-weekly Seven Days.

Sanders represents Vermont, where gun ownership is high but murders via shooting are low. In 2005, he voted in favor of a bill that protects gun makers and sellers from being sued. Meanwhile, Hillary Clinton has said that she'll attempt to repeal the bill, should she be elected.

Sanders has said that "sensible gun-control legislation" is needed, so long as it doesn't infringe on the rights of responsible gun owners.
