  Motivated by the supersymmetric interpretation of the CDF ee\gamma\gamma plus
missing energy event and the reported Z->bb excess at LEP, we analyze the
Higgsino as a cold dark matter candidate. We examine the constraints as implied
by the collider experiments, and then calculate its relic density. We find that
this Higgsino-like lightest supersymmetric particle is a viable cold dark
matter candidate (0.05 < Omega h^2 < 1), and we discuss its favorable prospects
for laboratory detection.
