It's official: Al Franken is the junior senator from Minnesota. The comedian-cum-politician was sworn in on Tuesday, giving the Democrats the 60th vote needed to override Republican filibusters. Franken joins the Senate after an eight-month standoff with his opponent, Republican Sen. Norm Coleman. He said that he envisions himself as a "people's proxy" in next week's confirmation hearings for Supreme Court nominee Sonia Sotomayor.
