Trump does exaggerate and engages in hyperbole. For example, when he says China runs the Panama Canal, he doesn't mean literally. And when he says Biden wants to get rid of gas heaters, the author engages in technicalities to prove Trump "lied" when in fact the effect is the same.
And yes, there are thousands of criminals murderers here as NBC (hardly a right-wing outfit) admitted.
This author reminds me of someone who says, "You lied! You said the color of the sky is blue when it's really indigo!"
