Security has been stepped up at synagogues and Jewish community centers across the Garden State after Saturday's mass shooting in Pittsburgh.

Police departments in Hoboken, Lakewood, Marlboro and more increased visible security as news of the shooting came in. The Essex County Sheriff's Office also sent patrol units to houses of worship of all faiths.

Sen. Bob Menendez condemned the massacre that left 11 people dead at the Tree of Life Synagogue and called for action.

"I am tired of standing in front of a camera saying our thoughts and prayers are with the families," Menendez said. "It's past time to do something."

Menendez also disagreed with President Donald Trump's claim that lives could have been saved if an armed guard was in the synagogue. He says the shooting shows the need for gun control legislation and a new assault weapons ban.

Gov. Phil Murphy says anti-Semitism is also on the rise in New Jersey.

"It may have been a Jewish community and synagogue in Pittsburgh but it is an affront on all of us," Murphy said. "And we have to do everything we can to eliminate that kind of evil and so we're pursuing a whole range of different avenues."

The governor has already signed some of the toughest gun laws in the country this year but says he wants to revisit the subject and work with the Legislature to introduce more gun safety laws.

The accused shooter, Robert Gregory Bowers, used an AR-15 at the SWAT team, according to police.
