President Obama will address the nation on Tuesday at 8pm Eastern time about the Gulf oil spill. The speech is expected to take 10-15 minutes.
Fox has already announced it will carry the speech and bump the starting time of its 2 hour Hells Kitchen back, but air the entire show.
No word from other broadcast networks yet, but ABC will likely shorten its Jimmy Kimmel Live or NBA Countdown pre-game show, and keep Game 6 of the NBA Finals telecast unchanged. CBS is scheduled to air repeats, and NBC has new Losing It With Jillian and America's Got Talent along with a Last Comic Standing repeat scheduled.
