“When you go to Disney, do they measure the number of hours you wait in line? Or what’s important? What’s important is, what’s your satisfaction with the experience?” McDonald said during a Christian Science Monitor breakfast on Monday. “And what I would like to move to, eventually, is that kind of measure.”

McDonald’s comments set off a political firestorm, with Republicans denouncing the remarks as inaccurate and inappropriate.

House Speaker Paul Ryan, R-Wis., called McDonald’s comments “flippant” and said they show “just how seriously the Obama administration’s VA is taking life or death problems” at the agency.

“This is not make-believe, Mr. Secretary. Veterans have died waiting in those lines,” Ryan said on Twitter.

McDonald took office in July 2014 after his predecessor was forced out amid a scandal over chronically long wait times at VA health care sites and reports that as many as 40 patients died while awaiting care at the Phoenix VA hospital. Similar problems were discovered at VA health sites nationwide, along with a widespread practice among VA employees of creating secret lists to cover up the long wait times and receive VA bonuses.

“There is nothing amusing about VA’s performance over the past few years, and comparing VA wait times to those of an amusement park is just plain wrong,” said Rep. Jeff Miller, R-Fla., chairman of the House veterans panel.

“Wait times are of critical importance to the veterans waiting for VA medical care and they should be to Secretary McDonald as well,” Miller said. “Unfortunately, nearly two years after McDonald took over at VA, the department’s wait-time rhetoric doesn’t match up with the reality of veterans’ experiences.”

Sen. John McCain, R-Ariz., chairman of the Senate Armed Services Committee and a longtime veterans’ advocate, called McDonald’s comment “outrageous and completely inappropriate,” especially since McDonald himself is an Army veteran.

“Our veterans aren’t in line for a theme park ride — they are in desperate need of timely access to quality medical treatment,” McCain said. “The VA secretary’s statement reflects a fundamental lack of understanding about the serious problems plaguing veterans’ health care.”

Citizens Against Government Waste, a nonpartisan watchdog group, said McDonald was “playing the role of ‘Dumbo’ in his very own ‘Fantasyland.’ Disney does, in fact, monitor how long its customers wait in line because they have the astonishingly simple belief that serving their customers quickly and efficiently is the best measure of overall performance.”

The group’s president, Tom Schatz, said in a statement that McDonald “seems ‘Frozen’ in the past, incapable of understanding that if veterans do not get an appointment in a timely manner, it could cost them their lives.”

VA spokeswoman Victoria Dillon said in a statement late Monday that officials know that veterans are still waiting too long for care.

“In our effort to determine how we can better meet veterans’ needs — knowing that their satisfaction is our most important measure — we have heard them tell us that wait times alone are not the only indication of their experience with VA and that’s why we must transform the way we do business,” Dillon said.
