Then he is a disgrace! Still I do not see the link with Trump.
Trump, as President, is in charge of the Executive branch. He resides in the White house and is responsible for messages emanating from there.
The only people I've ever seen argue that holocaust day should not be mentioned or that Jews should not be singled out for mention on that day (because other people suffered too, say the whiny babies) are people of the alt right and white nationalists groups who also argue that the holocaust is a hoax "to promote Jewish interests."
"Other people suffered, shut up about Jews" is literally their talking point and no one else's. And they are celebrating this.
