Nadezhda Tolokonnikova, best known for her role in the Russian Punk band “Pussy Riot” appeared Friday at the International Students for Liberty Conference in a Bernie Sanders tee-shirt.

The conference, composed primarily of libertarian-minded college students, largely rejects Sanders, but nonetheless found common ground with Tolokonnikova on social issues such as drug policy and criminal justice.

In 2012 some of the members of Pussy Riot were arrested in Russia after speaking out again President Vladimir Putin.

They have since been released and continue to promote activism through music.
