I agree with your comments on how social media is full of speculation and misinformation but I wouldn't immediately declare this statement as something that is "true" or "false". As others have mentioned underneath this post, this is more of an opinion someone has posted on Twitter, not a factual claim. I think in general it is also good to go into social media without making any assumptions, as no one shares (or truthfully shares) their personal information, credibility, or knowledge, you don't know if they know Trump or not, so it is best to look at social media with an unbiased and neutral approach.
