Trump says he never met Putin, now. In the past, he said he did. I just did a search for "trump met putin" and found a bunch of news sites reporting that in a GOP debate a while ago Trump said
“I got to know him very well because we were both on ‘60 Minutes,’ we were stablemates, and we did very well that night.”
Trump was boasting in that debate about nothing, they were on the same episode of 60 minutes but they were not even on the same continent for that episode.
That's not really the point. The point is Trump is now saying he hasn't, but in the past he said he has. Not only is he contradicting his earlier statement, but it also makes him not trustworthy. And of course, if he was boasting about having supposedly met Putin in the past, that means he thought it was a good thing to boast about, which suggests that he is sympathetic to Putin and to Russian interests.
“I got to know him very well because we were both on ‘60 Minutes,’ we were stablemates, and we did very well that night.”
