On Sunday, when Hillary Clinton left an event commemorating the 15-year anniversary of the 9/11 attacks early, due to what later was confirmed to be pneumonia, it validated what many of her detractors believed to be true: that the Democratic presidential nominee is too weak and unhealthy to hold one of the most important jobs in the world.

But Patton Oswalt isn’t buying into that angle. On Sunday night, the comedian flipped the narrative on its head, saying that campaigning through pneumonia is a sign of strength, not weakness.

Wait, so Hillary has PNEUMONIA and she's still campaigning as hard as she is? You realize how badass that is, right? — Patton Oswalt (@pattonoswalt) September 11, 2016

He then compared Clinton’s temporary ailment to Trump’s seemingly permanent one.

Psychotic, dissociative narcissism with lack of empathy > pneumonia. #ImWithHer — Patton Oswalt (@pattonoswalt) September 11, 2016

And reposted two other tweets by Business Insider senior editor Josh Barro that made a similar point.

I'm not sure it's right, but there's an argument to be made that this episode will improve Clinton's image. — Josh Barro (@jbarro) September 11, 2016

It shows her doing her best to grit her teeth and work hard even with pneumonia. And it's humanizing, relatable. — Josh Barro (@jbarro) September 11, 2016

And this one, too.

Reach back in time to when you have been sickest in your life. Do you remember that feeling? Do you remember how it felt to have to pull yourself out of bed and pretend that everything is fine at work? Certainly, that took tenacity on your part. Just as it did for Clinton.
