  Recent Spitzer observations have revealed a substantial population of z~2
ULIRGs with deep silicate absorption (\tau_{9.7}>1). This paper reports a 20cm
radio study of such a sample to elucidate their physical nature. We discover
that a substantial fraction (40%) of deep silicate absorption ULIRGs at z~2 are
moderately radio-loud with L_{1.4GHz}=10^{25}--10^{26}WHz^{-1}. This is in
strong contrast with z<1 radio galaxies and radio-loud quasars where none of
the sources with available IRS spectra have \tau_{9.7}>1. In addition, we
observe radio jets in two of our sources where one has a double lobe structure
~200kpc in extent, and another shows a one-sided jet extending ~90kpc from the
nucleus. The likely high inclination of the latter, coupled with its deep
silicate absorption, implies the mid-IR obscuration does not share an axis with
the radio jets. These sources are highly obscured quasars, observed in the
transition stage after the birth of the radio source, but before feedback
effects dispel the ISM and halt the black hole accretion and starburst
activity.
