"How About..." and "What About..."

Adverbial Objective and "A While" Reading "How About..." and "What About..." 1 minute Next Parentheses

These begin idiomatic expressions that are asking questions. They are followed by an interrog. The confusion comes, I think, because there is no verb in the expression.

...How about John? Did he go with you?
...What about the report? Did it get filed on time?

Happy punctuating!
