Congress cannot approve an illegal program when so many questions remain unanswered.

It is clear that this illegal program violates our Constitution and laws governing surveillance. The president's false choice between securing our nation and preserving our Constitution must be rejected. Congress has an obligation to determine the truth, especially since the administration is unwilling to check itself. Hearings like this help ensure steps are taken so the rule of law is respected by all, even the president.

It is way too early to make such bold assertions when so many questions remain unanswered and many thousands more may die in decades to come.

When presidents have overstepped the rule of law, history demonstrates how it undermined our core freedoms. We hope that Congress will assert its proper oversight role and demand accountability from the administration. The American people deserve no less from their government. Freedom and liberty must not be trumped by presidential power.

As Congress comes back to work out the differences in the House and Senate bills to reauthorize the Patriot Act, a commitment to freedom must prevail. The more we learn about the Patriot Act, the clearer it is that too much power was granted to the government, with too few safeguards against abuse. While neither reauthorization bill is perfect, we call on Congress to use the Senate bill as its guide as it reconsiders the Patriot Act.

I think one of the fundamental roles of Congress is to exercise oversight of the executive branch. And it's not happening.
