Three informed sources reported today, Monday, that the Democratic presidential candidate Kamala Harris's choices for vice president have been narrowed down to Pennsylvania Governor Josh Shapiro and Minnesota Governor Tim Walz. Harris is expected to announce her choice by tomorrow, Tuesday, before her first public appearance with her running mate at Temple University in Philadelphia. The sources noted that it remains unclear whether Harris has made her final decision. The vice president will embark on a five-day tour covering seven swing states likely to determine the outcome of the November 5 election. The sources mentioned that Harris has narrowed her search by interviewing three candidates: Walz, Shapiro, and U.S. Senator Mark Kelly at her residence yesterday, Sunday.
