Narrative:
Descending into ZZZ while on a vector to final ATC advised us of VFR traffic at our 12 o'clock position. We thought we could see the traffic just before it entered a cloud that we were about to fly over and had verified the traffic on TCAS. The aircraft was climbing; and when it was about 200' below us we received a climbing TCAS RA. Ca smith who was flying at the time took evasive action in compliance with the TCAS RA. I notified ATC of the response action; and we returned to normal flight moments later.[this event was caused by] another pilot [who] chose to operate his/her aircraft in clouds without a clearance.aircraft within close proximity to class C airspace should be required to be in contact with a controller at all times.
