Former President Barack Obama is set to embark on a crucial campaign tour in support of Kamala Harris as the election approaches. In a bid to rally support across key battleground states, Obama will kick off his campaign in Pittsburgh next week, marking the beginning of a four-week blitz aimed at energizing voters. This initiative comes as Democrats look to solidify their presence in swing states. Obama's efforts will include multiple stops in Pennsylvania and other pivotal locations as he seeks to enhance Harris's visibility and boost her campaign leading up to Election Day.
