The Russian punk rock collective Pussy Riot released a video on Tuesday calling for the dismissal of charges filed against protesters who sang in the Wisconsin’s state capitol last summer to protest the administration of Gov. Scott Walker (R).

The Associated Press reported that the video specifically calls on Wisconsin’s Attorney General J. B. Van Hollen, asking him to drop charges filed in more than 400 arrests.

In the video, Nadezhda Tolokonnikova and Maria Alyokhina said “Solidarity with Wisconsin!” and made their plea on behalf of the protesters, who began the daily singing demonstrations in the capitol in 2011.

The protests sprang up in the winter of 2011 in response to Walker’s effort to strip public employee unions of their ability to collectively bargain.

Van Hollen’s office declined to comment.

Recently, the Tolokonnikova and Alyokhina were attacked in a McDonald’s restaurant in the Russian city of Nizhny Novgorod. A group of Putinist thugs sprayed green-colored disinfectant into the faces of the women and their team and pelted them with garbage and debris.

The men chanted “Go to America!” as they beat the women, who suffered head injuries and chemical burns in the assault.

The women spent nearly two years in Russian prison camps for their protest in Moscow’s largest Russian Orthodox church. They were released prior to the 2014 Winter Olympics in Sochi, a move they dismissed as a publicity stunt by Putin to soften his image as a brutal dictator.
