Narrative:

Given clearance by ZMA to descend from 6000 ft to 5000 ft. Noticed we had traffic 12 O'clock position and climbing in our descent path. When TCASII alert sounded, ATC asked if we could turn 20 degrees left away from traffic. I had already turned and started to climb away from traffic at this point. ATC came back on frequency very flustered. Apologized for the traffic conflict and stated that the target had just popped up. Continued flight.
