From SOTU:

Inside the United States, where the war began, we must continue to give
homeland security and law enforcement personnel every tool they need to defend
us. And one of those essential tools is the PATRIOT Act, which allows Federal
law enforcement to better share information, to track terrorists, to disrupt
their cells, and to seize their assets. For years, we have used similar
provisions to catch embezzlers and drug traffickers. If these methods are good
for hunting criminals, they are even more important for hunting terrorists. Key
provisions of the PATRIOT Act are set to expire next year. The terrorist threat
will not expire on that schedule. Our law enforcement needs this vital
legislation to protect our citizens ? you need to renew the PATRIOT Act.
