Vice President Kamala Harris has officially secured the Democratic nomination for president and is in the final stages of selecting her running mate, having shortlisted six candidates. Among those being considered are Governors Andy Beshear and JB Pritzker, Senators Josh Shapiro and Mark Kelly, and Transportation Secretary Pete Buttigieg. Harris is reportedly conducting interviews with these candidates, with an announcement expected by Tuesday. Shapiro and Kelly are viewed as front-runners, though there is speculation that she may also be informing some candidates that they will not be chosen. The choice of running mate is critical for Harris as it could significantly impact the campaign's success. The formal announcement is anticipated to coincide with a campaign rally in Philadelphia next week.
