The Daily Worker was a newspaper published in Chicago founded by communists, socialists, union members, and other activists. Publication began in 1924. It generally reflected the prevailing views of members of the CPUSA; it also reflected a broader spectrum of left-wing opinion. At its peak, the newspaper achieved a circulation of 35,000. Contributors to its pages included Robert Minor and Fred Ellis (cartoonists), Lester Rodney, David Karr, Richard Wright, John L. Spivak, Peter Fryer, Woody Guthrie and Louis F. Budenz.

Robert Berkeley "Bob" Minor, alternatively known as "Fighting Bob", was a political cartoonist, a radical journalist, and, beginning in 1920, a leading member of the Communist Party USA.
