Bernie Sanders stood on a stage in front of a crowd of union workers inside the River Church Arena in Anaheim, Calif., demanding the Walt Disney Co. defend its billions and profits and its millions in salary for their CEO while some of their workers earn less than a living wage.

It was part of a barnstorming effort by the former presidential hopeful ahead of Tuesday’s primaries in California. Sanders also attended a rally in downtown Los Angeles supporting criminal justice reform, standing alongside progressive activists Shaun King and Patrisse Cullors (a Black Lives Matter co-founder).
