Confederate flags posters with cotton attached were found in several areas at American University Tuesday night, according to a statement from the school.

“This evening, ten confederate flag posters with cotton attached to them were reported in three locations on campus - Battelle, McKinley and Mary Graydon Center. [University] Police and the Office of Campus Life are investigating and we will notify the community when more information is known,” said Fanta Aw, vice president of campus life at the Washington D.C. school, in a statement.

The posters read, “Huzzah for Dixie.”

Aw’s statement noted that Tuesday night historian Ibram X. Kendi, a faculty member at the school was giving a presentation called “A Vision for Equality.”

The talk was an introduction to the Antiracist Research and Policy Center, a new initiative from American University that Knedi will lead.

“AU is committed to the vision of the Center and Dr. Kendi’s work and we will not be deterred by this cowardly attempt at intimidation,” continued Aw’s statement.

The center’s announcement came just a few days after another racially charged incident in May that involved bananas being hung by nooses, according to American University’s student paper the Eagle. The bananas had AKA written on them which corresponds to Alpha Kappa Alpha, a sorority whose membership is mainly black, according to the school.

The student government also issued a statement condemning the violence.

“The American University Student Government is infuriated by the Confederate flag posters with cotton bushels,” read the statement. “The significance of this occurring as our country continues to struggle with its history of white supremacy also cannot be ignored.”
