It’s definitely a bad look, especially given recent events, but I suspect this is a fairly common practice regardless of candidate.
When I took a journalism course we talked about this. It's not an uncommon practice to be given the questions ahead of time. Not for every interview of course, but quite a few. Especially when talking to the government. I had to do a few interviews for a magazine piece I was working on about jet noise over Whidbey island naval air station. They wanted the questions ahead of time.
