As Vice President Kamala Harris and her team race to vet potential running mates following President Joe Biden’s departure from the 2024 race, Sen. Mark Kelly (D-AZ) is emerging as an asset who could help counter one of Harris’s biggest weaknesses: the administration’s handling of the border crisis.

Sources have confirmed Kelly is being vetted by Harris’s team. A former Navy pilot and NASA astronaut from a working-class family in New Jersey, the Arizona senator already has a strong resume made even more impactful by his powerful advocacy against gun violence after his wife, then-Rep. Gabrielle Giffords, survived an assassination attempt during a mass shooting in 2011.
