(CNN) A day after Nike announced Colin Kaepernick as the face of the brand's 30th anniversary ad campaign, a city mayor in Louisiana issued a memo banning the purchase and use of any Nike products at the city's booster clubs and recreation departments.

"Under no circumstances will any Nike product or any product with the Nike logo be purchased for use or delivery at any City of Kenner Recreation Facility," the memo read.
