Does anyone want to guess how this will play out?

Today at 2:30 p.m., the clock runs out on the latest deadline for the White House to turn over materials regarding the National Security Agency's eavesdropping program to the Senate Judiciary Committee.

The documents were originally subpoened on June 27th and were to be turned over to the committee on July 18th. After a request from the White House the deadline was extended until today, and now White House Counsel Fred Fielding is saying that the gathering of the documents is, "by no means complete," and wants another extension. Last week Committee Chairman Patrick Leahy said:

...he'd wait no more. "You have rejected every proposal, produced none of the responsive documents, provided no basis for any claim of privilege and no accompanying log of withheld documents."

And when the White House ignores this latest deadline, what will Leahy do? Will he issue another sternly worded letter or will he act to find the administration in contempt of Congress?
