Mitt Romney was "glitter bombed" Tuesday in Colorado and now a student is facing criminal charges.
Glitter bombing is a form of protest where a person throws a fist full of glitter at another.
Peter Smith, 20, glitter bombed the Republican presidential candidate to protest his "general political philosophy," according to Reuters.
It's something that has traditionally been associated with gay rights activists, but this time it was just meant as a general opposition to Romney's stances on the issues.
Smith is a student at the University of Colorado Boulder.
Smith was removed from the campaign event immediately after he tossed the glitter. The Secret Service and local removed Smith.
Romney was also glitter bombed at an event in Minnesota, which he quickly spun to the crowd.
"This is confetti," Romney said with regards to the glitter. "We just won Florida. We're just going to win the White House next."
In Colorado, Smith was questioned overnight and charged with misdemeanors of creating a disturbance, throwing a missile and an unlawful act on school property.
Smith could face up to six months in jail and a $1,000 fine if convicted, according to reports.
The attack is not an isolated incident, though. Romney was just the latest to have glitter hurled at him. Newt Gingrich, Ron Paul and Rick Santorum have all faced similar situations.
Former Republican candidate Tim Pawlenty was hit with glitter last year while on the campaign trail.
The incident, while not uncommon, is being prosecuted more often.
Outspoken politicians, like former Arkansas Gov. Mike Huckabee, have called for increased prosecution for what some call "assault."
Though the glitter did not create any lasting damage or cause Romney any physical harm, it is something authorities are taking more seriously.
It is unclear how severe of a punishment Smith will receive for his actions. The student is not denying responsibility, but defending his actions as a simple form of protest.
