A senior administration official says that NATO will not likely take command and control of the overall mission in Libya on Wednesday (as President Obama announced in his speech last night) -- that the full transition will likely be delayed.
The transition will be pushed further in the week, but "no more than a day or two," the official said, adding that this is "not unexpected" and "not unusual."
The official said that media reports of delays "are legit, but minor in the big picture," adding that the process "will take just a bit longer to play out."
"It is a major muscle movement," the official said.
