Sunday on “State of the Union,” tightening poll numbers in the presidential race, and the heated debate over Bain Capital. Candy talks exclusively with Former Republican Presidential Candidate Rudy Giuliani, and DNC Chair Debbie Wasserman Schultz.

On Memorial Day we remember those who have died in service to our country by taking an account of how we care for our veterans. Last year, we explored the challenges facing veterans. A year later we check back with our guests to measure progress:

General Peter Chiarelli (ret.), Fmr. vice chief of staff of the U.S. Army on treating PTSD and brain injuries in veterans.

Senator Patty Murray, chairwoman of the Veterans Affairs Committee, on the V.A.’s struggle to break the backlog of disability claims.

Tim Tetz, Legislative Director of the American Legion, and Paul Rieckhoff, Founder and Executive Director of Iraq and Afghanistan Veterans of America on the challenges our nation’s veterans have in finding a job in a struggling economy.
