A gay rights activist threw glitter at Rep. Michele Bachmann Saturday as the congresswoman was leaving Right Online, the conservative blogger's conference taking place in Minneapolis this weekend.

The Minnesota representative kept on walking and waving at the crowd after she wrapped up her speech to the group, and barely flinched as she was doused by the "rainbow" flecks of plastic.

The activist, identified by the Minnesota Star Tribune as Rachel E.B. Lang, later told conservative blogger Ed Frank that she did it to bring light to Bachmann's support of an anti-gay marriage initiative in the state.

"She can run but she can't hide from her record of support for anti-gay extremists. So today, I welcome her into the glitter hall of fame," Lang told the blogger.

Bachmann becomes the third Republican presidential candidate to get the glitter treatment. Former Minnesota Gov. Tim Pawlenty and former House Speaker Newt Gingrich both had glitter tossed at them during recent book signings.

Lang called the attack "a really good-natured, light-hearted way to bring attention to an important issue, which is gay rights."

But taken to task over whether throwing objects -- even tiny, light-reflective ones -- accomplishes anything, Lang said, "Everyone has to choose their own way to get your message across and as long as you're not hurting anyone it's all legitimate."
