Narrative:
Both RA's were with bwi approach. The first we were never advised of conflict and deviated 400 ft above 4000 ft assigned altitude. Aircraft second RA we were advised when RA was underway. Deviated 400 ft above 10000 ft assigned altitude. ATC was advised both times. ATC was very busy the first time but the second was with a citation that was cleared to climb through our altitude.
