I believe the funeral for Corey was yesterday, Trump did NOT attend Secret Service told him not to go
Trump also did not want to make the event a spectacle because of the necessary security measures.
He did call Corey’s wife,Helen, earlier this week, as well as the other two men who were injured.
I believe Trump didn’t attend for obvious security reasons. I imagine the media would have ruined the solemn ceremony by squealing Trump was trying to make it all about himself. One thing we can safely assume is that Trump will keep contact and not abandon any of these families like evil creepy Joe did those soldiers who died at Abbey Gate.
