I was working Clearance Delivery; Flight Data and Ground Control and was Controller in Charge (CIC). The Local Controller was certified [recently]. The Local Controller had several arrivals; departures; and a Cessna in the pattern for full stop taxi-backs. During the time of the incident I was handling some CIC duties; numerous phone calls; one of which was a fellow controller calling for sick leave for the rest of the week which needed to be entered into web scheduler; also had some Flight Data tasks. I believe I was working on a reroute at the time and the ASOS hourly alarm was sounding to prepare the hourly METAR.While this was going on; Local control requested the runway be his control for his pattern traffic. I heard an aircraft call from the ramp ready to taxi. In the following minutes I taxied him to the active runway with the necessary crossings and continued with the other duties. I missed that I had crossed a now active runway or that an aircraft cancelled his takeoff roll. The incident was brought to the attention of the Air Traffic Manager (ATM) a week later by the pilot of the Cessna who aborted his takeoff; who in turn informed me of the event. The pilot reported that he got his aircraft up to almost 25 mph before cancelling and turning off at the first intersection. The traffic crossed at the next intersection down the runway.I believe I let myself get distracted with phone calls; CIC duties; and administrative work while my Ground Control duties were not as busy at the time; which led to a breakdown in communication and coordination with Local Control. I should have been more vigilant with a newly certified Local Controller on position and focused more on my position duties than on the phone calls and CIC/administrative duties. I will do my best to avoid such situations again and keep my priorities focused on the operation.
