Narrative:
Air carrier X departed iad on a 260 degree heading. I climbed air carrier X to 5000 ft. Air carrier Y departed behind air carrier X. I asked air carrier Y her heading. She said 260 degrees. I called traffic to air carrier Y in an attempt to apply visual. Air carrier Y did not have traffic in sight.
