Man throws glitter at Santorum for his anti-LGBT views

A bump in the Iowa caucus polls isn't the only thing Rick Santorum has received over the past week.

During a campaign spot in Johnston, Iowa Friday evening, the Republican presidential candidate was greeted by an unidentified man upset over Santorum's negative views on the LGBT community.

Within a second of shaking the former Pennsylvania senator's hands, the man threw glitter right into Santorum's face.

"Stop the hate!" he shouted. "Taste the rainbow!"
