As investigations continue into whether Wednesday's bloody attack in San Bernardino, California, was an act of terrorism, Hillary Clinton urged people to remember that most Muslim Americans are just as traumatized as everyone else.

“President Obama spoke this morning about the possibility that it was terror-related," Clinton said Thursday during an appearance in Manchester, New Hampshire. "I’m confident that they will get what happened and take whatever steps are necessary to prevent future attacks."

“It’s important to remember," she continued, "the vast majority of Muslim Americans are just as concerned and heartbroken about this as anyone else. No matter what motivation these killers, these murderers had we can say one thing for certain: They should not have been able to do this.”

Clinton then called on Congress to "overcome the intimidation of the gun lobby.”

The former secretary of state reiterated a point that President Barack Obama has brought up in the wake of the attack.

“Making sure that people on the terrorist watch list can’t buy weapons,” Clinton said. “If you are too dangerous to fly in America, you are too dangerous to buy a gun in America. How could anyone, anyone of good conscience disagree with that?”

Clinton was speaking on a panel at the Women’s Economic Opportunity Summit at Southern New Hampshire University in Manchester.

On Thursday, she was endorsed by the U.S. Women’s Chamber of Commerce, which has 500,000 members. It was the chamber’s first presidential endorsement.
