The ceiling was 1;000 and the visibility was better then 3 miles; so we were VFR. A CRJ aborted take off on Runway XXL. An A320 was on ILS XXL just inside the outer marker. An A330 was on Taxiway 'E' that crosses the far end of Runway XXL; but does not intersect the runway. A call went out that the CRJ aborted take off by Local Two. Local One stated after the fact that he was going to keep the A330 taxiing on Taxiway 'E'. I never heard the coordination about keeping the A330 rolling. I never remember giving an acknowledgement to that coordination as I was finding out the reason for the abort. The CRJ was able to clear the runway prior to A320 crossing the landing threshold. As I was looking at the ASDE to check the runway I saw that the A330 had crossed the extended centerline of XXL and was also clear. I asked Local One what was that all about and he said he had coordinated it but I never heard anything or acknowledged anything and never advised the A320 of the crossing traffic at the far end. Well when A320 was exiting the runway he gave me an ear full about how his instruments were deviating so much that he almost went around. Recommendation: get an acknowledgment before crossing aircraft and just don't yell out and go. The other Local has to coordinate with the aircraft.
Tower Controller described a probable loss of runway separation and the likely interference with the ILS signal when an aircraft was issued a runway crossing clearance; intra-facility coordination failures were listed as casual factors.
