New Jersey Gov. Chris Christie (R) late Friday vetoed a bill to ban a powerful model of assault weapon that he initially advocated in the wake of last December's elementary school shootings in Newtown, Conn.

The bill that passed New Jersey's Democratic legislature would have prohibited the Barrett .50 caliber long-range rifle. Although Christie this spring proposed a ban on future sales of the firearm, he vetoed the ultimate bill because he said it went too far, requiring residents who already own the rifle to give theirs up.
