HOW TRUE? NIA DG "Diverted" Jonathan's 2015 Campaign Funds

From what we gathered soon after the election, ex-President Goodluck Jonathan's close men had insisted that some people should return the huge cash they collected to be deployed for the PDP campaign, because they failed to use the money for the required purpose.

Could the recovered Ikoyi Billions be part of such money?

But why will GEJ and PDP give cash to NIA DG for campaign, an agency that should be neutral?
