Update: John Podhoretz in Commentary said that the failure to mention Jews was intentional, and an effort at "inclusion." Source here.
Virginia Senator Tim Kaine appeared on Meet the Press on Sunday, January 29, 2017. A portion of the transcript is below. (Source)
Senator Tim Kaine said ....the irony is not lost on me that [the White House restrictions on travel by Muslims into the US] was issued the same day as the White House issued their Holocaust Remembrance Day proclamation that unlike any previous administration removed all reference to Jews. So you put a religious test on Muslims and you try to scrub reference to Jews in the Holocaust Remembrance. This was horribly, horribly mishandled. So it's not a pause in--
That's a tough charge--
SENATOR TIM KAINE:
--a traditional sense.
--Senator, that's a tough charge. You think it's more than a coincidence that it all happened on Friday?
SENATOR TIM KAINE:
I think all of these things are happening together. When you have the chief political advisor in the White House, Steve Bannon, who is connected with a news organization that traffics in white supremacy and anti-Semitism and they put out a Holocaust statement that omits any mention of Jews.
Remember, earlier administrations have done these statements. And so the first thing you do is you pull up to see what earlier statements have said. And the earlier statements, President Obama, President Bush always talk about the Holocaust in connection with the slaughter of Jews.
The final solution was about the slaughter of Jews. We have to remember this. This is what Holocaust denial is. It's either to deny that it happened or many Holocaust deniers acknowledge, "Oh yeah people were killed. But it was a lot of innocent people. Jews weren't targeted." The fact that they did that and imposed this religious test against Muslims in the executive orders on the same day, this is not a coincidence.
