According to a source, the call lasted five minutes during which Clinton told Judy Scott that she knows the family is going through a difficult time and that bereaved mother has shown such grace during the ordeal.
Clinton also told Scott's mother that if elected president she would work to ensure that similar tragedies don't continue to happen.
Earlier today, Clinton addressed the shooting during a campaign event with community leaders in Orangeburg, S.C. Clinton called the incident a "terrible tragedy" and reiterated her push for the widespread use of body cameras.
"I think the terrible tragedy in Charleston which led to the indictment, was the result of seeing the facts," Clinton said.
Clinton is currently in South Carolina after swings through Iowa and New Hampshire following her official kick-off rally in New York City last weekend.
During an event today at the Trident Technical College in North Charleston, Clinton rolled out new policies to reduce youth unemployment and called for tax credits for businesses that offer apprenticeship programs to young people.
"When employers invest in on-the-job training, workers are more productive and businesses are more profitable," Clinton explained. "This is one of these economic strategies that is win-win-win for everybody."
