ABC and CBS didn't air any impeachment coverage today, at least not nationally. A Price is Right fan in Sacramento said KOVR pre-empted it today, however.
NBC's entire coverage was optional. As a result, some stations aired Days today while others did not. NBC gave two opportunities for stations to switch to programming, at 3:00 and 4:00 Eastern.
WXIA Atlanta did not air any coverage at all today. WNBC New York aired the coverage until 3:00, although Ellen was already programmed for 4.2 COZI, so it aired on both stations, and both Kelly and Ellen were properly listed on COZI today instead of the usual shows. WVIT Hartford aired the coverage until 4:00. WTHR Indianapolis, WDIV Detroit, and WCBD Charleston, SC all aired the coverage until 5:00. WBBH Fort Myers and WILX Lansing, MI both ended the coverage at 2:00 Eastern and switched to Dr. Oz. KTAL Shreveport, LA and KYTV Springfield, MO did not air the first hour of coverage in favor of local news, but did switch to it at 1:00 Central and did not air Days.
