We have a phone call he did with 25 other people on the call, as if he would intentionally try to break the law on a call like that, with the party being "bribed" apparently unaware of the bribe. I think to try to bribe, you actually have to try to bribe.
There is a transcript of Clinton asking the UK PM to investigate something to help out during the election season. So, I think there is a sense that Trump is once again being targeted by the Swamp for things the Swamp does all the time.
Any investigation of Trump is pretty much DOA right now. All of them were launched because he is Trump, not because there was evidence of a crime that is always investigated. The investigations start with a target (Trump) and try to end with a crime, instead of starting with a crime...which is not how we are supposed to do things in the United States. Remember, the coup started the day he was elected.
It is interesting to see someone cry "wolf" 20 times for a couple years, and then wonder why no one comes when he cries "wolf" the 21st time. Maybe there is a wolf this time. But, I would think you could understand why no one thinks there is.
