Word is that KTRK in Houston scrapped their Sunday morning newscasts, due to some technical problems.
Mike McGuff says that in the 6 and 7am newscast spots were Good Morning America and This Week with George Stephanopoulos. The same GMA episode that aired at 6am, re-aired at 7am.
The station did post about their technical problems on their Facebook page:
ABC13 is undergoing some maintenance work. We are working to return you to our regular programming as soon as possible. Thank you for your patience.
