New Jersey U.S. Senator Bob Menendez says he's enormously frustrated that he can't get a vote on the Senate floor on tighter gun control bills. The New Jersey Democrat visited the Essex County Police Academy to see the power of an AR-15 assault rifle, similar to the one used in the deadly Florida school shooting. Menendez says the military style weapon doesn't belong on the street. He supports a reauthorization of the now expired assault weapons ban.
