One sorority issued an apology...
"Theta Zeta Chapter of Delta Delta Delta sincerely apologizes for offending members of the UT and Austin communities with the fiesta-themed event held on Thursday, September 20. Tri Delta does not condone cultural insensitivity or racism. Tri Delta was founded on the idea of being “kind alike to all,” and we use this principle to guide us as we strive to adhere to high moral standards and strength of character. Chapter officers and advisors are working together to insure that our standards are upheld in the future and that chapter members understand they are responsible for the conduct of their guests."
And Wow...
This guy flipped off a group of minority students marching against racism.
