Trump brags of military's 'Hydrosonic' missiles at campaign rally (that's actually a toothbrush brand)

Is Trump's own staff trolling him, or is he that feeble-minded? Maybe both. President Donald J. Trump, speaking at yet another campaign rally before a maskless crowd today, said something really dumb.

Trump just bragged about the military's "Hydrosonic" missiles.

Hydrosonic is a toothbrush brand.
