I have a suspicion that Dotard is cracking under the pressure of the Russia collusion investigation, a suspicion that things are heating up, hitting closer to home for him... what other reason would he have to tweet this out?
Fake News reporting, a complete fabrication, that I am concerned about the meeting my wonderful son, Donald, had in Trump Tower. This was a meeting to get information on an opponent, totally legal and done all the time in politics - and it went nowhere. I did not know about it!
This contradicts his earlier narrative that the meeting was about the adoption of Russian babies. I suspect that Donald Jr is going to be taken in for interrogation by Mueller's people, and that his dad is shitting a brick over it. There are allegations that Trump pere used to smack his son around in front of other people. If that is true, I imagine he will be regretting that if his son decides that he doesn't want to be a fall guy for his father.
Tengrain has a really good post on this topic, including some funny takes regarding Trump 'sacrificing his eldest son for the good of the country'. I really think Junior needs to figure out that his dad means for him to take the fall before it's too late.
