  We present evidence for a dual Active Galactic Nucleus (AGN) within an
early-type galaxy at z=0.709 in the Extended Groth Strip. The galaxy lies on
the red sequence, with absolute magnitude M_B=-21.0 (AB, with h=0.7) and
rest-frame color U-B=1.38. Its optical spectrum shows strong, double-peaked
[OIII] emission lines and weak Hbeta emission, with Seyfert-like line ratios.
The two narrow peaks are separated by 630 km/s in velocity and arise from two
distinct regions, spatially resolved in the DEIMOS spectrum, with a projected
physical separation of 1.2 kpc. HST/ACS imaging shows an early-type (E/S0)
galaxy with hints of disturbed structure, consistent with the remnant of a
dissipationless merger. Multiwavelength photometric information from the AEGIS
consortium confirms the identification of a dust-obscured AGN in an early-type
galaxy, with detections in X-ray, optical, infrared and radio wavebands. These
data are most readily explained as a single galaxy harboring two AGN--the first
such system to be observed in an otherwise typical early-type galaxy.
