RENEE MONTAGNE, HOST:
And this is the day of the week when we normally talk to our MORNING EDITION contributor Cokie Roberts about politics. This morning, though, politics and the runup to the president's State of the Union Address tomorrow have been overshadowed by the news out of Rome.
So we've asked Cokie, a longtime Vatican watcher, to weigh in on the announcement that Pope Benedict is resigning at the end of this month.
And good morning, Cokie.
