  We study the generalization of the Kerr-Newmann black hole in 5D
Einstein-Maxwell-Chern-Simons theory with free Chern-Simons coupling parameter.
These black holes possess equal magnitude angular momenta and an event horizon
of spherical topology. We focus on the extremal case with zero temperature. We
find that, when the Chern-Simons coupling is greater than two times the
supergravity case, new branches of black holes are found which violate
uniqueness. In particular, a sequence of these black holes are non-static
radially excited solutions with vanishing angular momentum. They approach the
Reissner-Nordstr\"om solution as the excitation level increases.
