Narrative:
En route from ord to dca, ZDC gave us 'expedite descent' from FL290 to FL260. Through FL265 we got a 'climb' RA and immediately climbed to FL275. I queried ATC about another aircraft and he immediately responded that there was an aircraft below us at FL250 who had a problem with his mode C which was reading 1000 ft high. After getting on the ground. I called ZDC and spoke with a supervisor. I explained situation and expressed that I would have appreciated knowing about the aircraft below with the mode C problem. Our RA maneuver was strong enough that a flight attendant fell. She was not injured.
