Sunday: Obama calls for VA accountability; Uproar in the NFL

(CBS News) -- We're going to spend a good deal of time this Sunday on Face the Nation talking about the ongoing inquiry into the Veterans Affairs department. The organization has been charged with fabricating data and covering up huge delays in treatment times for its beneficiaries. The president spoke out Wednesday after almost three weeks of silence, vowing "to make sure there is accountability." And VA Secretary Eric Shinseki issued a statement late Thursday pledging, "We will act." He went on: "I fully agree with President Obama's statement (Wednesday) 'If these allegations prove to be true, it is dishonorable, it is disgraceful.' "

We'll speak with Democratic Sen. Richard Blumenthal, D-Conn, who thinks the FBI should be involved in preserving evidence in this case, since there could be criminal implications to some of the misconduct. Also joining us are Rep. Adam Kinzinger, R-Ill., who served as a veteran in Iraq and Afghanistan, and Republican Sen. John Thune.

Plus, we'll take a look at the lawsuit against the NFL by former players, who say they were provided heavy doses of addictive, painkilling drugs by the league, masking serious injuries.

We'll also have two all-star panels to tackle the week's news.

To discuss the turmoil at the V.A. and to commemorate Memorial Day, we'll be joined by Dana Priest, of the Washington Post, whose reporting on poor treatment of wounded veterans at Walter Reed Hospital won a Pulitzer Prize. David Finkel, also of The Washington Post, is a Pulitzer Prize winner and author of "The Good Soldiers," about his time embedded with the U.S. military in Iraq. His new book is "Thank You For Your Service." Tom Manion wrote "Brothers Forever: The Enduring Bond between a Marine and a Navy SEAL that Transcended Their Ultimate Sacrifice," about his son and his son's best friend who died in service in Iraq and Afghanistan. The two were honored by President Obama in his Memorial Day address in 2011.

We'll also discuss the recent NFL lawsuit with Steve Silverman, the attorney representing players in the case, as well as sports reporters Jarrett Bell of USA Today and Sean Gregory of Time.

Finally, we'll take a look back at some of the greatest bits of wisdom from this year's college commencement addresses.

There is a lot to talk about, and we hope you'll join us.
