Using data from the MOSDEF survey, we present a census of AGN-driven ionized outflows in a sample of 159 AGNs at 1.4 < z < 3.8, the largest such sample at z ~ 2. We detect outflows in 17% of the AGNs, seven times more often than in a mass-matched sample of inactive galaxies in MOSDEF. The outflows are fast and galaxy-wide, and exist in galaxies along and across the star-forming main sequence. We investigate the relations between outflow kinematic, spatial, and energetic properties and both AGN and host galaxy properties. The power of the outflows is primarily determined by AGN bolometric luminosity and the kinetic coupling efficiency is largely unchanged over cosmic time, therefore AGN-driven outflows are more energetic at z ~ 2, where luminous AGN are the most prevalent. In addition, I will present recent results of extended [O III] emission in a nearby quasar.
