Vice President Kamala Harris is set to make her first solo visit to the US-Mexico border in more than three years, focusing on immigration as a key campaign issue amidst a challenging polling landscape compared to Donald Trump. Her trip, planned for a border community in Arizona, aims to confront criticism regarding her immigration record and project toughness on border security. Harris is expected to call for tougher security measures and address the flow of fentanyl, as her campaign seeks to regain ground with voters. This visit comes at a time when immigration is becoming increasingly critical in the lead-up to the 2024 election, and Harris looks to flip the narrative surrounding her approach to the topic.
