While Senate Democrats seem eager to move a longer Patriot Act extension, the House might take a slower road. House Democrats hotly opposed any extension until thorough hearings are held, and Republicans promised to hold hearings during the three-month extension.

As of Friday morning, President Obama had not signed the extension, but is expected to, possibly over the weekend.
