Posters spotted around the Twin Cites with a four-letter vulgarity followed by a Minnesota Congresswoman's name have some asking who's responsible. It turns out, the posters are promoting an upcoming hip-hop concert. In a few weeks, the group G-BIZ will perform at Big V's Saloon. Group member Matt Ernster came up with the idea for the poster displaying the four-letter word followed by Michelle Bachmann 2010. He also created a song with the same title. 5 EYEWITNESS NEWS contacted Bachmann's campaign office, they called the posters "juvenile" and "disgusting." Bachmann's congressional office did not respond.
