Critic questions how Atiku established private university six years before first licenses

I built my private university (ABTI) in 1993, before becoming VP, Atiku replies Tinubu

#ME:
The first Private Universities in Nigeria are:

1. Igbinedion University, Okada
2. Madonna University, Okija
3. Babcock University, Ilishan-Remo

They were licensed by the NUC in 1999.

So how come Kachalla Wole Wole Atiku Abubakar built his own private University in 1993, six years before NUC started granting license to establish private university in Nigeria?

Meanwhile, Atiku left Customs in 1989 as Deputy Director. Where did Atiku, a civil servant get money to build a private university, four years after retirement?
