Adweek is reporting that NBC's special report at 2:30 ET/1:30 CT/12:30 MT/11:30 PT will be optional, so affiliates airing "Days" at that time can choose either to air "Days" or air the testimony.
"NBC News will provide an optional special report, which means NBC stations can choose whether or not to take it. Lester Holt will anchor from New York. ABC will provide a network-wide special report (which won’t make many General Hospital fans very happy). CBS News will carry a special report hosted by Scott Pelley."
