This has nothing to do with news.  These two don't like each other and this has been going on for two years.
Both the reporter and mayor are grandstanding.  Move on...   

Very similar to the Pete Doocy/Jen Psaki exchanges in the first few months of the Biden administration. Doocy would start off by saying "certain people have criticized the President because..." and Psaki would immediately ask "Who?". They would spar back and forth for a few minutes before Doocy would admit that the "certain people" was Donald Trump. Not very enlightening from a public policy perspective, but worthwhile for viewers who wanted to get a look at the give-and-take of a presidential press conference.

I honestly can't say I've explored the details behind this story. What I found refreshing is to see a reporter actually challenge one of these power puffed people and not take a B.S. answer as the end of it, like too many of them do. "OK, got my clip for the 6 PM news. That's enough!" Meanwhile, the official gets away without saying anything. 

It's the same reason I so often praise Vassy Kapelos. It's like trying to pin Jello to the wall getting a straight, non-talking point answer out of the politicos from every party, but she keeps going and going, often asking the same question three times in three different ways to try and pull out an honest, real response.

When they don't give her one, at least she's shown discerning voters that the guy or gal never answered the question. 

We need more of that. 

My favourite canned answer is one that tends to follow someone dying before their time. It's more song and dance than song, and it goes something like this: "The public's (or whoever's) safety is our number one priority."
