TeVatron Direct CP Violation Results

I report some recent results on direct CP violation measurements in hadronic decays collected by the upgraded Collider Detector (CDF II) at the Fermilab Tevatron: CP-violating asymmetries in the two-body non-leptonic charmless decays of $b$-hadrons, the first reconstruction in hadron collisions of the suppressed decays $B^{-}\to D(\to K^{+}{\pi }^{-})K^{-}$ and $B^- \to D(\to K^+\pi^-)\pi^-$,andthemeasurementofTPasymmetriesinthe$B^{0}_{s} \to \phi \phi$ decays.
