That was Fake News. It was a group called Bend the Arc started by Alex Soros. They sent a press release claiming that the 11 people who signed their protest were “Jewish leaders” and the compliant news media reported it that way.
I looked at the leadership list of the Jewish Federation of Pittsburgh on their website, and not a single one of the 11 people who signed the letter is on the list. If you google them, you will find that the 11 signatories are lightweights and political neophytes (there is one who graduated from Columbia Law School and practices employment law, but he is the exception).
Then, the community Jewish leaders should immediately come forward and denounce this group, because it is front and center, such as being reported by WAPO, “thousands sign letter saying Trump was not welcome.” USA Today, Pittsburgh Jewish leaders to Trump, don’t come until you denounce white nationalism. People, Esquire, Washington Times and many more are reporting the same thing and if that’s the case then local news is reporting the same.
It is now up to the Jewish community, because if my President isn’t welcome there, to represent this ENTIRE country that is in mourning, then that is shameful.
