VA firestorm to lead Sunday talk shows

A growing political firestorm over allegations of treatment delays and secret wait lists at veterans hospitals nationwide will likely dominate Sunday news shows. 

The top official for veterans' healthcare Robert Petzel resigned Friday, one day after testifying before a Senate panel over allegations that some VA facilities deliberately hid long wait times for patients, resulting in at least 40 deaths in an Arizona VA hospital. VA Secretary Eric Shinseki, who faces calls to resign, said he was "mad as hell" after being grilled by lawmakers in Thursday's hearing.

House Republicans scheduled a vote for Wednesday on legislation that would give Shinseki expanded authority to fire senior executives at the agency and its 152 medical centers.

Other topics on the shows include the 60th anniversary of Brown v. Board of Education, and sexual assault on college campuses.

Here's the lineup: 

CBS' "Face the Nation" will talk with White House chief of staff Denis McDonough about the latest developments surrounding the Veteran Affairs investigation.
