Republican Gov. Jeff Landry signed legislation Wednesday requiring a poster-sized display of the Ten Commandments in "large, easily readable font" in all public classrooms, from kindergarten to state-funded universities.

"I can't wait to be sued," he said after signing HB 71.

"The law violates the separation of church and state and is blatantly unconstitutional," the ACLU, ACLU of Louisiana, Americans United for Separation of Church and State, and the Freedom from Religion Foundation said in a statement.
