At long last, enough members of Congress have rediscovered their primary reason for being there at this defining time in U.S. history -- to rescue the disappearing Constitution.Sen. Ron Wyden, a Democrat from Oregon who is a member of the Senate Select Intelligence Committee, is joining with Colorado Democrat Sen. Mark Udall to "introduce legislation that would limit the federal government's ability to collect data on Americans without a demonstrated link to terrorism or espionage."No doubt stirred by the recent revelations of Edward Snowden, Wyden and Udall are moving to fully awaken Americans and others of the U.S. government's limitless spying on us. Furthermore, Wyden is insisting on public hearings because, as he said last month, "the American people have the right to expect straight answers from the intelligence leadership to the questions asked by their representatives."But why stop there? Barack Obama should be in the witness chair as well.And there is also a strong bipartisan drive to reopen the Patriot Act, which was passed in a panic by Congress soon after 9/11.
