"Face the Nation" Sunday, May 19

Coming up this Sunday on "Face the Nation," we'll continue the discussion on the September 11th attack in Benghazi. Plus the two newest scandals in the nation's capitol, Associated Press reporters' phone records being subpoenaed by the Justice Department without their knowledge and the IRS targeting conservative groups seeking tax exempt status. The Administration already removed IRS Commissioner Steven Miller. What's next?

We'll start with White House Senior Advisor Dan Pfeiffer. Then we'll hear from the other side - Sen. John Cornyn (R-Texas) and Rep. Jason Chaffetz (R-Utah). Cornyn is the #2 Republican in the Senate and has been involved in the Senate Finance Committee's attempt to get answers from the IRS. Chaffetz has been a key player in the investigation led by the House Oversight Committee into what happened in Benghazi on the night of September 11th and what happened in the aftermath with the so-called "talking points" used by UN Ambassador Susan Rice when she appeared on five Sunday shows just days after the attacks that killed four Americans.

The President and CEO of the Associated Press Gary Pruitt will also join us to discuss the Justice Department's investigation into possible leaks involving a foiled terror plot in Yemen last year - should the government have access to reporters' phone records without first notifying them?

Then we'll turn to our roundtable with the New York Times' David Sanger, POLITICO's Lois Romano, The Washington Post's Dan Balz and CBS News Political Director John Dickerson. They'll delve into all of this and more.

It's a lot, but that's why it's "Face the Nation." Check your local listings and tune in on Sunday morning.
