The Special Adviser to the President on Media and Publicity, Dr Reuben Abati, said in a statement in Abuja that the signs were offensive and repugnant to Jonathan and many Nigerians.
The statement said: “Jonathan wholly shares the widely expressed view that the signs, which were put up without his knowledge or approval, are a highly insensitive parody of the #BringBackOurGirls hash tag.
“Jonathan appreciates the enthusiastic show of support for his administration by a broad range of stakeholders.
“But he condemns the #BringBackJonathan 2015 signs which appear to make light of the very serious national and global concern for the abducted Chibok girls.
“The president assures all Nigerians and the international community that his administration remained fully engaged with efforts to rescue the abducted girls.
“He will not knowingly promote any actions that will fly in the face of the seriousness of their plight and the anguish of their families.”
