Video from of the incident, available above from WCSC-5, shows that the candidate appeared to take the glittering in stride. The Los Angeles Times reports that the protesters were escorted out of the auditorium.

Lindsey Boerma, a reporter for CBS News and The National Journal, tweeted a picture of the glitter mid-air from another perspective:

This isn't the first time Santorum has been the target of glitter. At an event in Iowa in December, a man who yelled "Stop the hate, taste the rainbow" threw glitter at the former Pennsylvania senator. And Real Clear Politics reported on Thursday, just two days before the South Carolina primary, that people protesting Santorum's stance on social issues at a rally in Mt. Pleasant, S.C. threw glitter at the candidate.
