Update: 6:20p PT: President Obama didn't finish speaking until about 9:18p ET so schedules and overnight ratings for ABC, CBS, NBC and FOX will be a mess.
CBS programmers tweeted that Live To Dance is moving to 9pm ET and that the original episode of The Defenders will stay at 10pm, so it looks like Criminal Minds is bumped for the week, but it was a scheduled repeat anyway.
ABC and NBC will interrupt normal programming to air the remarks which were originally expected last less than 10 minutes now may go as long as 20 minutes. Update 3:25p PT, ABC will preempt Better With You. Update 2: Fox apparently decided to air the remarks too, preempting the 8pm Human Target and running a repeat of Raising Hope.
