Trump told the Times that he simply went to say hi to Melania at that dinner, and then had a few words with Putin who just happened to be sitting there too oh gee Vlad I didn’t even know you were there.
Starting at 47 seconds you can watch Trump signaling to someone – witnesses say it was Putin – in schoolboy gesture language: You, me, we talktalk? You want to? Me, you? Ok?
Or, was he offering a blow job? Just saying…
That is one very plausible interpretation, yes.
