“My father and I marched with Martin Luther King Jr. through the streets of Detroit.”
If he was saying it figuratively, he would NOT have added the “through the streets of Detroit” part.
My advice to Mitt? Quit digging. Admit you lied, say you’re sorry, and move on.
Well, the stories often interchange “Grosse Pointe” and “Detroit”, so I don’t see what the problem is with that. And we know for a fact that Romney marched in a Martin Luther King Freedom March in 1963 in Detroit, that is in Grosse Pointe.
