At the Democratic National Convention (DNC) in Chicago, Bexar County Sheriff Javier Salazar criticized Donald Trump, labeling him a 'self-serving man' who undermines border security efforts and hinders progress for political gain, contrasting his actions with those of Vice President Kamala Harris, who has actively fought against trafficking. Day 3 of the convention will feature Minnesota Governor Tim Walz delivering the keynote address as he accepts the vice-presidential nomination, alongside performances and speeches from notable Democrats including Bill Clinton and Nancy Pelosi. The evening's theme, 'A Fight for Our Freedoms,' aims to highlight the commitment of the Democratic Party to protect civil liberties and to showcase Walz's record as a champion for working families. Anticipation builds around the potential appearance of Oprah Winfrey, who previously endorsed Barack Obama, although her endorsement of Harris remains uncertain. Amidst the festivities, the DNC is also addressing serious issues such as the threat of drone attacks in New York City. Overall, the event is marked by a tone of celebration and unity among Democrats as they prepare for the upcoming elections.
