A petty, bush league comment by President Trump.
As someone else said, not much upside, and potentially more downside.
There is no downside. I would exhume that traitor and dump his body in the mexican desert where it belongs.
My guess is PDJT is pissed off because he KNOWS something is coming down from mueller and the corrupt state. And traitors like Mcstain and the rat bastard Jeff Sessions were integral in making this coup possible.
