WASHINGTON (AP) — Key administration figures from the intelligence world are set to appear before the House Judiciary Committee to answer another round of questions about the government's surveillance of Americans' phone records.

Six weeks after a leaked document exposed the scope of the surveillance, many Democrats and some Republicans are still angry about it.

The questioners Wednesday include the Republican who sponsored the USA Patriot Act, which governs the collection of phone records. Congressman Jim Sensenbrenner of Wisconsin has said he is "extremely troubled" by the administration's legal interpretation that permitted the government to gather hundreds of millions of Americans' phone records.

The panel's ranking Democrat, congressman John Conyers of Michigan, has said he fears the U.S. is on the verge of becoming a surveillance state.
