Although I have been on the fence about Trump, I agree with you. And I do admire him for taking a stand here.
“Google and Fox announced Tuesday afternoon that an anti-Trump Muslim advocate, Nabela Noor, would be allowed to play a role in the debate. She was apparently chosen by Youtube, with help from the RNC and Fox. African American, Mark Watson, and Latino, Dulce Candy will also join the moderators in the debate to ask the candidates a question on an issue that matters to them and their communities.”
