Santorum gets "glitter-bombed"

JOHNSTON, Iowa -- Republican presidential candidate Rick Santorum was greeted with a fistful of glitter as he arrived at his final campaign event Friday night.

An unidentified man shouted "Stop the hate! Taste the rainbow!" as he threw glitter at the former Pennsylvania senator before being ushered out of Okoboji Grille, where Santorum was scheduled to watch Iowa and Oklahoma in the Insight Bowl. Santorum nonchalantly brushed the purple glitter off his shoulders and walked away without acknowledging the man.

"Glitter-bombing" has becoming the emerging form of protests of certain gay rights activists. Presidential candidate Newt Gingrich was glitter-bombed at a book signing in September. The socially conservative Santorum has made family values and opposition to same-sex marriage central planks of his campaign.
