A few days ago Donald Trump took to Twitter to defend his son, Don Jr. regarding a meeting with a Russian operative before the 2016 election. In doing so he contradicted his earlier tweets about the same meeting.

Maybe this is special counsel Robert Mueller’s real strategy. Get real close to Trump without actually touching him and wait for him to flinch. Mueller’s got Trump’s campaign manager, his personal lawyer, maybe his son (and son-in-law) and Trump gets nervous and tweets out something that basically says, “What I said earlier was a lie. Here’s the real story.”

It must be really agonizing for Trump to watch Mueller’s activities slowly play out, kind of a Chinese water torture. Tweeting may make Trump feel good, but I’m guessing Mueller feels even better.
