From “Bad Call” by Charlie Hurt in the NYPost:

University of Virginia professor Larry Sabato said the phone call was inappropriate.
“Rudy was rude. Nobody does this. Can you imagine a president doing that? ‘Can you wait a second, folks. It’s my wife on the line?’ ” Sabato said.
“There are only two possibilities to explain this. It’s an example of his weirdness or an attempt to show late in life that he has family values. You expect this from a teenager experiencing puppy love.”
