I guess it would depend on if it really happened or not. If there were news cameras capturing all the images and the police arrested him, then most likely the Repubs would not react like that. If, instead, there was someone looking for publicity stating they saw Trump shoot Cohen on 5th avenue, but no other evidence, then I would suggest the Repubs would rightly play the get-all-the-facts game.
But let’s flip it for a second…isn’t the reaction you are attributing to Repubs about Trump pretty much exactly the reaction you are getting from the Dems about Ellison? Don’t get me wrong…I’m not saying it is okay for anyone to commit a crime and yes, they should all be punished. But from a political coverage…you have a woman and her son with video tape showing Ellison physically and verbally abusing her. And yet the Dems are covering for him and playing the get-all-the-facts game. Is that really any different? Oh, the severity of the crime, sure, but the political reaction?
