Narrative:

While on gcn (ground control north) I had 2 aircraft under tow; holding waiting to cross at different locations. One holding short of rwy 8L at L7 and one short of runway 8R at M11. I instructed tug X to cross runway 8R to which he replied 'crossing runway 8R'. Tug X was actually holding short of runway 8L and begin to cross runway 8L instead. At the same time aircraft X was beginning his takeoff roll on runway 8L. Asde-X alerted and aircraft X aborted and returned for takeoff.crossing was issued during a relief briefing. Next time let the relieving controller issue the crossing.
