  We present preliminary measurements of the cross section and the double
longitudinal spin asymmetry in inclusive jet production in polarized p+p
collisions at Sqrt(s) = 200 GeV. The measured cross section agrees well with
NLO pQCD calculations over seven orders of magnitude. The observed spin
asymmetries are consistent with theoretical evaluations based on deeply
inelastic scattering data and tend to disfavor a large positive gluon
polarization.
