It doesn't have to be a deep fake. You can get better results with your run of the mill Hollywood CGI. Look at the date on this video.

Or a lookalike. I’ve seen better impersonating on the Hollywood strip, giving selfies with you for a fiver.

Second vid is deep fake voiced by another person, the eyes are unfocused and blurry as they are in those videos

That's two different things, beings, creatures, holograms, whatever you want to call it. That is clearly not the same person. This is actually really fucked up.

I am little behind on this. Are both of these videos released from White House?
