Why are Nigerians upset with President Goodluck on Daughter's Wedding?

The marriage of Elisabeth Sakwe, the adopted daughter of Nigerian president Goodluck Jonathan, has caused an uproar in the country. The extravaganza wedding was broadcast on national television and leaves a bitter taste in the mouth of concerned Nigerians. 

The picture below has not helped the president and could even tarnish his presidential election after the news broke that a gold plated designed iPhone by luxury designer Michael Malivelihood were offered to wedding guests by the president. Were these expensive gifts financed by the federal or state fund?

A tweet from Michael Malivelihood tried to defuse the controversy by claiming that the iPhone
were gifts from his design agency for the newlyweds and their guests, and had nothing to do with the government.
