CNN Airs Clip of Bush Rehearsing

CNN aired President Bush false-starting his immigration speech from the Oval Office on Monday night!
The embarrassing images and audio [16 seconds total] captured the president starting and stopping his message, then looking at an unseen director for guidance.
"The president is rehearsing and the network pool inadvertently went to the president as he is rehearsing," anchor Wolf Blitzer explained.
FOXNEWS, MSNBC, CBS, ABC and other outlets did not air the 'rehearsal.'
NBC NEWS, which was operating the television camera in the Oval Office, said late Monday that it gave the president a cue to begin his speech too early.
The slip comes just six months after CNN mistakenly placed a bold black 'X' mark over Vice President Cheney's face as he gave a speech.
