'Only in America do we see this kind of carnage': Newsom
California Gov. Gavin Newsom traveled to Half Moon Bay on Tuesday, offering strong words after three mass shootings have rocked the state in recent days.
"It's said all the time -- only in America," Newsom said during a press briefing. "No. 1 in gun ownership, no. 1 in gun deaths, it's not even complicated."
"The one common denominator are these damn guns," he continued. "I've got no ideological opposition to someone owning gun responsibility. But what the hell is wrong with us that we allow these weapons of war and large-capacity clips out on the streets or sidewalks? Why have we allowed this culture, this pattern to continue?"
Newsom applauded California's gun safety measures, though said, "One state can't do it alone," and criticized the Republican party for blocking gun safety reform "every step of the way."
"Only in America do we see this kind of carnage, this kind of chaos, this kind of destruction of communities and lives," Newsom said.
Five men and two women were killed in the Half Moon Bay shooting. A male survivor is currently hospitalized in stable condition, authorities said.
The workers were shot "execution-style," California Rep. Anna Eshoo said. The sheriff's office did not provide any further details amid the investigation.

Workplace violence believed to be motive
Workplace violence is believed to be the motive for a gunman who opened fire at two Northern California farms on Monday, killing seven and injuring one, authorities said.
All victims -- seven men and one woman -- were adults, authorities said. The victims were of Asian and Hispanic descent, authorities said.
The suspect’s semi-automatic handgun was legally purchased, authorities said.
The suspect, 67-year-old Chunli Zhao, worked at one of the shooting locations, Mountain Mushroom Farm, but it's unclear what connection he may have had with the victims beyond being co-workers, authorities said.
Zhao was not known to police, according to authorities.
Zhao is expected to be arraigned on Wednesday. Prosecutors will review the case and decide on charges, officials said.
The coroner's office is working to notify the victims' next of kin, but authorities said it's difficult to reach families because some victims are migrants.

Biden calls for federal assault weapons ban after California mass shootings
President Joe Biden released a statement on Tuesday in the wake of the deadly mass shootings in Half Moon Bay and Monterey Park, California.
"Jill and I are praying for those killed and injured in the latest tragic shooting in Half Moon Bay, California," Biden said. "For the second time in recent days, California communities are mourning the loss of loved ones in a senseless act of gun violence."
"Following a briefing from my homeland security team, I have directed my administration to ensure local authorities and the broader Half Moon Bay community have the full support of the federal government in the wake of this heinous attack," the president added.
On Monday, two days after another deadly mass shooting in Monterey Park, Sens. Dianne Feinstein (D-Calif.), Richard Blumenthal (D-Conn.) and Chris Murphy reintroduced a federal ban on assault weapons as well as legislation that would raise the minimum purchase age to 21. In his statement on Tuesday, Biden said that while “we await further details on these shootings, we know the scourge of gun violence across America requires stronger action.”
"I once again urge both chambers of Congress to act quickly and deliver this Assault Weapons Ban to my desk, and take action to keep American communities, schools, workplaces, and homes safe," the president said.
