Remember: The richest 1% evade over $160 billion in taxes every year.
That amount would fund SNAP for a year with money to spare.

NEW: After ICE used tear gas on kids setting up for a Chicago Halloween parade, Pritzker asked DHS to keep Halloween ICE free, for kids' safety. Kristi Noem just said "No". 😶 Show this to every moron who insists conservatives "care for the children."😢

President Leon Botstein’s essay, “Autocracy and the university in America today,” is free to read for one week. "In the immediate term, the greatest danger facing the American university... is the loss of independence perpetrated by a profoundly anti-intellectual government,” he writes.

Happy birthday to Ruby Bridges, who turns 71 today.
The decision to integrate Ruby Bridges’ school was a result of the landmark Supreme Court case Brown v. Board of Education, which ruled segregation unconstitutional.
4 years later, in 1964, Rockwell painted her story "The Problem We All Live With".
