Lawmakers and congressional aides poked holes in Department of Veterans Affairs Secretary Bob McDonald’s Wednesday argument that accountability has returned to the agency because it has fired more than 3,700 people in the last two years.

The VA has been the focus of a scandal involving a systemic effort across the country to hide the long wait-times veterans faced when seeking medical care through the agency. That scandal has led to calls for officials to be fired, but just a few have been fired and many have either been given new jobs or allowed to retire.
