We don't even know what's going on with some of the other investigations. I think Mueller's being downplayed by the GOP and blown up by the Dem's.
It was good. Some decent soundbytes, Mueller confirmed that Trump wasn't innocent, and it actually got Trump to shut the **** up about it a little bit, I think.
That being said, I think the taxes will be just as damning, and hopefully more so. Mueller basically said that he didn't know if Trump and his idiots were smart enough to know they were breaking the law intentionally. Which, sadly, I kind of agree with. I think Trump was completely ignorant of how the law works up until he made his statement about taking help again and got his ass firmly handed to him from multiple people. Then he learned, 'Oh, I actually can't take information'. That caused him to backpedal.
When it comes to taxes I really and truly don't feel that defense will work. Sure, the Trump Tower meeting was sketchy, but you can feign ignorance. A few decades of tax fraud\evasion is not as easy to skate on. Those investigations also aren't being handled by the DOJ, they're being handled by the House.
