More than 44,000 people have signed an open letter from progressive Jewish leaders saying President Trump is not welcome in Pittsburgh until he denounces white nationalism. Eleven members of the Pittsburgh affiliate of Bend the Arc: A Jewish Partnership for Justice penned a letter to Trump following Saturday's shooting at the Tree of Life synagogue that left 11 congregants dead. "President Trump, you are not welcome in Pittsburgh until you stop targeting and endangering all minorities," the letter reads. "President Trump, you are not welcome in Pittsburgh until you cease your assault on immigrants and refugees."
