Here, Dan Coats, the Director of National Intelligence learns that Trump has invited Putin to Washington:
"That's going to be special." I am presuming that Coats is referring to "special" as in "riding the short bus", not as in "extraordinary".
Trump thinks that Helsinki went well, despite every sentient Republican telling him otherwise. So Trump does what any moronic gambler does who finds himself deeply in the hole: He doubles down on his bet.
Trump and Putin reached a secret verbal agreement. With the example of how Trump "negotiated" with Kim Jong-un, Trump probably gave Alaska back to Russia in exchange for a set of nesting dolls.
Putin is an expert at playing people. Putin is known for meticulously preparing for meetings with foreign leaders (as do the North Koreans). Trump likes to wing it. The results seem to be along the lines of some peckerwood who thinks he can shoot getting into a match with
Jerry Miculek.
Trump prepared for the summit by getting into "Blame America First" mode by blaming the U.S. for bad relations with Russia.
of course, the Russians loved that.
Let's be clear about this: The Republican base is siding with their party leader who has openly and repeatedly taken Russia's side in matters pertaining to American-Russian relations. These are the same people, mind you, who get upset at football players taking a knee during the National Anthem, but they support a man who is in Russia's pocket because they think they can work with him.
History may not repeat itself, but it does rhyme.
