Francine Busby, the local party chair, said she wished she could say she was shocked by reports of another mass shooting.

“But these are so commonplace that we are never shocked anymore,” she said in a statement. “Horrified. Frustrated. Scared for our children. But not shocked.

“The scale and proximity of the attack in San Bernardino is what we find shocking. This hits so close to home. Many San Diegans have roots in San Bernardino and are hoping and praying for the safety of family and friends. Our hearts go out to them.”

Busby said it was time attention and resources are focused to protect “American lives at home with the same determination that we do abroad.”

“It is time for our leaders to stand up, grow a collective backbone, and organize to defeat the gun lobby and bring about commonsense reforms that would save lives,” she said.

“When our hopes are not enough, our voices and our votes are the only way to stop this madness.”

The 11 a.m. attack reportedly came at a holiday party.

“We have no information at this point to indicate this is terrorist-related,” said San Bernardino Police Chief Jarrod Burguan. “Obviously … we have a domestic terrorist type situation.”

The San Bernardino Police Department first said in a tweet that it had “confirmed 1 to 3 possible suspects” and multiple victims in the shooting and called it an “active shooter” incident 60 miles east of Los Angeles.

The county Sheriff’s Department is providing updates via Twitter.

Marybeth Feild, president of the Inland Regional Center helping disabled people, told The Associated Press that the shooting was near a building that houses a library and conference center where at least 25 people work. According to the San Bernardino County sheriff, authorities were searching for one to three people. The attackers were heavily armed and were possibly wearing body armor, according to San Bernardino police spokeswoman Sgt. Vicki Cervantes. The Inland Regional Center is one of 21 facilities serving people with developmental disability run by the state, according to a California official. People were evacuated from the structure. City Hall was on lockdown, a councilman told CNN. Reuters contributed to this article.
