As the US presidential election approaches, Donald Trump continues to express unsubstantiated concerns about election integrity during a campaign event in Pennsylvania. He suggests that widespread fraud is a threat, pushing for immediate results on election night. Meanwhile, Democratic candidate Kamala Harris emphasizes the importance of voter participation and has already cast her ballot. Recent polls show a tight race between the two, with Harris leading in several swing states, but facing losses in critical areas like Pennsylvania. The outcome remains uncertain as both candidates make their final appeals.
