The tombstone had the phrase "Made America Hate Again!" engraved under Trump's name. Instagram user Sachin RB said he took the photo around 8 a.m. near Sheep's Meadow.
Park authorities removed the tombstone shortly after, but few people had already snapped photos of it, according to Sachin RB.
A park authority confirmed to PIX11 News that the headstone was found and has been removed.
It's still unclear who put the tombstone there.
