OK, here is his previous statement on FISA: this statement:

I strongly oppose retroactive immunity in the FISA bill.
Ever since 9/11, this Administration has put forward a false choice between the liberties we cherish and the security we demand.
The FISA court works. The separation of power works. We can trace, track down and take out terrorists while ensuring that our actions are subject to vigorous oversight, and do not undermine the very laws and freedom that we are fighting to defend.
No one should get a free pass to violate the basic civil liberties of the American people – not the President of the United States, and not the telecommunications companies that fell in line with his warrantless surveillance program. We have to make clear the lines that cannot be crossed.
That is why I am co-sponsoring Senator Dodd’s amendment to remove the immunity provision. Secrecy must not trump accountability. We must show our citizens – and set an example to the world – that laws cannot be ignored when it is inconvenient.

And here ishis current statement over the just passed FISA “Given the grave threats that we face, our national security agencies must have the capability to gather intelligence and track down terrorists before they strike, while respecting the rule of law and the privacy and civil liberties of the American people. There is also little doubt that the Bush Administration, with the cooperation of major telecommunications companies, has abused that authority and undermined the Constitution by intercepting the communications of innocent Americans without their knowledge or the required court orders.
“That is why last year I opposed the so-called Protect America Act, which expanded the surveillance powers of the government without sufficient independent oversight to protect the privacy and civil liberties of innocent Americans. I have also opposed the granting of retroactive immunity to those who were allegedly complicit in acts of illegal spying in the past.
“After months of negotiation, the House today passed a compromise that, while far from perfect, is a marked improvement over last year’s Protect America Act.
“Under this compromise legislation, an important tool in the fight against terrorism will continue, but the President’s illegal program of warrantless surveillance will be over. It restores FISA and existing criminal wiretap statutes as the exclusive means to conduct surveillance – making it clear that the President cannot circumvent the law and disregard the civil liberties of the American people. It also firmly re-establishes basic judicial oversight over all domestic surveillance in the future. It does, however, grant retroactive immunity, and I will work in the Senate to remove this provision so that we can seek full accountability for past offenses. But this compromise guarantees a thorough review by the Inspectors General of our national security agencies to determine what took place in the past, and ensures that there will be accountability going forward. By demanding oversight and accountability, a grassroots movement of Americans has helped yield a bill that is far better than the Protect America Act.
“It is not all that I would want. But given the legitimate threats we face, providing effective intelligence collection tools with appropriate safeguards is too important to delay. So I support the compromise, but do so with a firm pledge that as President, I will carefully monitor the program, review the report by the Inspectors General, and work with the Congress to take any additional steps I deem necessary to protect the lives – and the liberty – of the American people.”

The immunity for the telecoms is still a part of the bill and it’s still a concern. Only 105 Democrats voted for it in the House. But apparently Reid says they will try to kill the immunity part of the bill which seems odd since it already passed in the Senate with much broader immunity. Reid knows it won’t be successful it’s only to provide cover for Obama. Obama can support the bill (for general election purposes — he certainly doesn’t want McCain beating him up over this) without supporting the immunity option (thus just barely saving himself from a charge of flip-flopping).
Obama will vote for the bill whether is has the immunity provision or not. And the left is not too happy (Um…not at all! Ouch!). Sorry, Obamanites but your guy does have to worry about the middle of America who wants their president to use every tool against the terrorists that he can (if that were not the case, Obama wouldn’t be supporting this bill). This will probably not be the last time he moves to the center, so I would get used to it if I were you.
But hey! There’s still hope, there hasn’t been a vote yet. Maybe he’ll decide to stand on principle instead of political expediency and vote against it. Well, have to wait and see. Next week is looking to be an interesting news cycle, don’t you think?
