We have taken long slit, medium resolution spectra of the gas disks in
the nuclei of a complete sample of 21 nearby radio-loud early-type
galaxies using the Space Telescope Imaging Spectrograph on board the
Hubble Space Telescope. We present our sample selection, observations
and data reduction along with initial interpretations of those
data. We find that the nuclei are all compatible with a single
kinematic class: rotating disks with high velocity dispersions of the
order of a few hundred km/s. We find broad nuclear components on the
scale of 1000 km/s in 62 percent of the sample.
