Sorta right:
“Where in the Constitution is the separation of church and state?” O’Donnell asked him.
Ok, with you there. It’s actually not in the Constitution. So far, so good. But:
When Coons responded that the First Amendment bars Congress from making laws respecting the establishment of religion, O’Donnell asked: “You’re telling me that’s in the First Amendment?”
Uhm, yes. it is. She later clarified her point was that there is no statement about separation in the constitution. And she’s right.
That fits the narrative. This doesn’t:
Chris Coons can’t name the five freedoms in the First Amendment
[…]
Coons named the separation of church and state, but could not identify the others — the freedoms of speech, press, to assemble and petition — and asked that O’Donnell allow the moderators ask the questions.
