Observing CP Violating MSSM Higgs Bosons at Hadron Colliders ?

We report on the possibility of observing Higgs sector CP violation of the minimal supersymmetric standard model at a hadron machine. The CP phase dependent cross-sections for the $VH_i$ associated production processes are given for the Fermilab Tevatron and CERN LHC. Substantial production cross-sections for channels of all three Higgs bosons simultaneously are shown to be possible, giving a drect indication of the CP violation. The observability of the Higgs signals are discussed.
