The last-minute election campaign of US Vice President Kamala Harris is gathering momentum, not least after an endorsement from former President Barack Obama. Despite still needing to officially clinch the Democratic nomination, she is viewed as the frontrunner for the ticket.

A big question remains however: who will be her VP pick?

Arizona Senator Mark Kelly has emerged as a lead candidate for many: the former astronaut and US Navy pilot is seen as a centrist voice in Congress.

Yahoo Finance’s Josh Lipton, Ben Werschkul and Rick Newman got into that conversation.

“It would be kind of a zag” says Washington correspondent Ben Werschkul, adding that the “signal you could send with Mark Kelly is a state like Arizona could be in play”. Ben adds that having been a key part of the CHIPS and Science Act, Kelly “would become an instant conduit to the business world”.
