In this edition of Greta Talk, we catch up with former Senator John Danforth (R-MO), who served nearly 20 years in the Senate. Senator Danforth (who is an ordained Episcopal priest) tells the On the Record host all about his new book The Relevance of Religion: How Faithful People Can Change Politicswhich discusses how faith and religion might be "the key to restoring our civic virtue".

In the calm and wise voice of the pastor he once aspired to be, Senator Danforth argues that our shared religious values can lead us out of the embittered, entrenched state of politics today. A lifelong Republican, he calls his own party to task for its part in creating a political system in which the loudest opinions and the most polarizing personalities hold sway.

Senator Danforth, who believes "politics is not in the realm of the absolute", also tells Greta Van Susteren what faithful people can do to try to fix broken politics, why separation of church and state is so important in America, and even says why there is something wrong with the tone of politics in general.
