It's so clear that some people are so consumed by their hatred for Trump that they can't see the forest for the trees.
The media, Rats and NT's all want to claim some huge crime has been committed if the POTUS with held aid to Ukraine until they initiated an investigation into what happened leading up to the 2016 election. If Trump did this it's not a crime. He is the POTUS and he sets foreign policy. If he demands a country receiving our aid do something to receive the aid it's not a crime.
The media go on and on about this because they hate Trump and they hope it will leads to ratings.
The Rats go on and on about this because it's all they've got to keep their base fired up going into the 2020 election.
The NT's go on and on about this because they can't admit Trump is actually doing a good job and they are just dumb.
