Harris says what she’s doing is ‘not new,’ but as president she would take a ‘new approach’ in puzzling answer

It sounds like Harris might be referring to introducing a new strategy or approach in the carrying out of a role or task that isn’t new itself. Often, people in roles of leadership or authority opt for ‘new approaches’ to reshape and improve existing policies, practices or systems. However, without more context, it’s difficult to surmise her exact intentions. If you could provide more information or the full context of her statement, I’d be happy to give a more accurate interpretation.
