Members of the Little Rock Nine the group of Black students who integrated Little Rock Central High School in the 50s have knocked Arkansas Education Department for barring students from receiving graduation credit in an Advanced Placement African American studies course, NBC News reported on Friday.

Elizabeth Eckford and Terrence Roberts spoke out following the states recent move, with the Education Department saying the decision on the course would stand until its determined whether it violates state law and teaches or trains teachers in CRT [critical race theory] and indoctrination.

The restrictions came after Arkansas Gov. Sarah Huckabee Sanders (R) signed the LEARNS Act into law earlier this year. It barred curriculum that would indoctrinate students with ideologies, such as CRT, according to Sanders executive order . The state is still set to offer an African American history course, according to the Education Department.

I think the attempts to erase history is working for the Republican Party , Eckford told NBC News. In 1957, Eckford was famously photographed at her Little Rock high school as white students stared and shouted.

They have some boogeymen that are really popular with their supporters, she told the outlet.
