A Democratic Socialists of America caucus argued the Constitution was created to protect slavery and wealthy people in a Monday video calling for a new founding document.

The DSA’s Marxist Unity Group, a caucus focused on mass movement-building, called on viewers to join the DSA and fight for a “big public assembly” to establish “a democratic socialist republic” under another constitution. The bold message comes after the organization received significant attention for its new “program” outlining radical policy priorities and saw three endorsed candidates win Democratic primaries in June.
