Observations of ionized and neutral gas outflows in radio-galaxies (RGs)suggest that AGN radio jet feedback has a galaxy-scale impact on the host ISM,but it is still unclear how the molecular gas is affected. We present deepSpitzer IRS spectroscopy of 8 RGs that show fast HI outflows. All of theseHI-outflow RGs have bright H2 mid-IR lines that cannot be accounted for by UVor X-ray heating. This suggests that the radio jet, which drives the HIoutflow, is also responsible for the shock-excitation of the warm H2 gas. Inaddition, the warm H2 gas does not share the kinematics of the ionized/neutralgas. The mid-IR ionized gas lines are systematically broader than the H2 lines,which are resolved by the IRS (with FWHM up to 900km/s) in 60% of the detectedH2 lines. In 5 sources, the NeII line, and to a lesser extent the NeIII and NeVlines, exhibit blue-shifted wings (up to -900km/s with respect to the systemicvelocity) that match the kinematics of the outflowing HI or ionized gas. The H2lines do not show broad wings, except tentative detections in 3 sources. Thisshows that, contrary to the HI gas, the H2 gas is inefficiently coupled to theAGN jet-driven outflow of ionized gas. While the dissipation of a smallfraction (<10%) of the jet kinetic power can explain the dynamical heating ofthe molecular gas, our data show that the bulk of the warm molecular gas is notexpelled from these galaxies.
