  We have detected FIRST J101614.3+520916 with the XMM-Newton X-ray
Observatory. FIRST J101614.3+520916, one of the most extreme radio-loud, broad
absorption line (BAL) quasars so far discovered, is also a Fanaroff-Riley type
II (FR II) radio source. We find that, compared to its estimated intrinsic
X-ray flux, the observed X-rays are likely suppressed, and that the observed
hardness ratio indicates significant soft X-ray photons. This is inconsistent
with the simplest model, a normal quasar spectrum absorbed by a large neutral
HI column density, which would primarily absorb the softer photons. More
complex models, involving partial covering, an ionized absorber, ionized mirror
reflection, or jet contributions need to be invoked to explain this source. The
suppressed but soft X-ray emission in this radio-loud BAL quasar is consistent
with the behavior displayed by other BAL quasars, both radio-loud and
radio-quiet.
