WTH, you don’t plant trees in August! You plant trees when they are dormant in the winter. That tree is at great risk of not having enough water and too much heat to make it.
I am a master gardener and a tree farmer, I know how trees survive past their first few years and when they can’t.
If you are a master gardener you must be aware of climate zones. In the north, many trees are planted going into fall. It’s really not that hot this time of year. Plus, anyone with a clue would be watering that tree on a regular basis.
As far as planting a tree in the winter, I’ll give you a shovel when it is 30 below zero and see how far down you can dig. :)

You’d have to use an ice auger to dig a hole in the perma frost where I live.
It’s ok. The White House has a permanent garden staff who will do everything necessary for the tree, including digging it up now that the ceremony is done and replacing it with a fresh one later if necessary.
