Narrative:

I was working ground control taxiing three aircraft from the ramp to runway 11 via east (from directly below the tower to the far west side). As the first two made their way west a fog began to roll in. I was waiting for aircraft a to come out the other side of the fog but it seemed to be taking longer than it should. I noticed aircraft Y begin his take off roll at the same time I found the aircraft X on the amass (airport movement area safety system) heading towards runway 11 on taxiway F. I yelled for local control to stop him and he canceled his take off clearance. Aircraft X keyed up as I attempted to reach out to him. He said that he must have taken a wrong turn and shouldn't he continue forward. I told him to hold his position and asked if he had room to make a 180 without entering the runway. I don't recall the exact answer but it was a no. Aircraft Y exited the runway and I asked local if I could enter the runway to turn him around. He said wait for the next lander which was aircraft Z. Aircraft Z landed exited at taxiway D (just before F). I was able to put aircraft a on to the runway and exited him at taxiway D as well west bound on taxiway F. The controller in charge (controller in charge) reported it downstairs to the supervisor and the supervisor reported it to whoever. However I overheard the conversation and no one repeating the situation mentions aircraft Z that still landed. I didn't want anyone to get in trouble should they pull tapes. I assumed when I asked to enter the runway that aircraft Z was being sent around. And I admit when he said he was landing I didn't argue. It maybe had been unsaid but I did think maybe a go around might add a problem in the weather even though aircraft X was outside the 'gate' on the amass he was facing the runway stationary. I believe it was handled the best way possible in all honesty. I just didn't want it to look like a possible event was being hidden.

Narrative: I was working Ground Control taxiing three aircraft from the ramp to runway 11 via E (from directly below the tower to the far west side).
