Host Bob Edwards talks to NPR's David Welna about the highly unusual year in Congress. Senate control passed to the Democrats, when James Jeffords of Vermont left the Republican Party. A huge projected budget surplus disappeared with President Bush's tax cut, the Sept. 11 terrorist attacks, and the war in Afghanistan. The House and a Senate office building closed because of anthrax contamination. And bi-partisan harmony vanished toward the end of the session with fighting over the budget and President Bush's anti-terrorist bill.
