The Chicago Teacher's Union is catching heat for a social media post that reverently remembered the legacy of Joanne Chesimard, who died in Cuba on Friday and was convicted of killing a New Jersey State Trooper decades ago.

"Rest in Power, Rest in Peace, Assata Shakur," the post on X said.

"Today we honor the life and legacy of a revolutionary fighter, a fierce writer, a revered elder of Black liberation, and a leader of freedom whose spirit continues to live in our struggle.

"Assata refused to be silenced. She taught us that 'It is our duty to fight for our freedom. It is our duty to win. We must love each other and support each other. We have nothing to lose but our chains.'"

Chesimard, also known as Assata Shakur, was 78 years old when she died of natural causes, the Cuban Ministry of Foreign Affairs said Friday.

Chesimard had lived in Cuba since 1979 after escaping from a New Jersey prison after being convicted of killing New Jersey State Trooper Werner Foerster in 1973.

She had been on the State Police's most wanted list for decades. A $2 million reward had been offered for her capture.

The union's social media post spurred criticism that it was honoring someone convicted of killing a police officer.
