  Chern-Simons AdS supergravity theories are gauge theories for the super-AdS
group. These theories possess a fermionic symmetry which differs from standard
supersymmetry. In this paper, we study five-dimensional Chern-Simons AdS
supergravity in a Randall-Sundrum scenario with two Minkowski 3-branes. After
making modifications to the D = 5 Chern-Simons AdS supergravity action and
fermionic symmetry transformations, we obtain a Z_2-invariant total action S =
\tilde{S}_bulk + S_brane and fermionic transformations \tilde{\delta}_\epsilon.
While \tilde{\delta}_\epsilon \tilde{S}_bulk = 0, the fermionic symmetry is
broken by S_brane. Our total action reduces to the original Randall-Sundrum
model when \tilde{S}_bulk is restricted to its gravitational sector. We solve
the Killing spinor equations for a bosonic configuration with vanishing su(N)
and u(1) gauge fields.
