LONDON — J.K. Rowling was not about to let inauguration day go by without at least one Donald Trump burn.

On Friday morning, following her already impressive display of unrelenting, Trump-targeted Twitter shut-downs, Rowling responded to the following tweet from journalist Terry Moran.

Trump says no POTUS ever had inaugural concert at the Lincoln Memorial. But GWB, Obama both did. Why make a claim so easily disproved? — Terry Moran (@TerryMoran) January 19, 2017

**Burn incoming**

It's either malignant narcissism, or a hitherto undiscovered form of inauguration-based and triggered amnesia. https://t.co/YhmPhi5hJ6 — J.K. Rowling (@jk_rowling) January 20, 2017

She certainly has a way with words, doesn't she?

Rowling wasn't about to be put off by trolls, either.

To wrap the whole thing up — at least for the time being — Rowling busted out her secret weapon: the Harry Potter reference.

Because we appear to be living in an alternative reality where dreadful things you thought were impossible can happen. #Inauguration pic.twitter.com/nxG0m7nDC1 — J.K. Rowling (@jk_rowling) January 20, 2017

That one's going straight to the top of the #inauguration hashtag.
