Vice President Kamala Harris faces intensified criticism from Republicans regarding her handling of the border crisis, especially following President Biden's withdrawal from the 2024 presidential race, which has made her the presumptive Democratic nominee. Critics argue that her policies, initiated under Biden, have contributed to a significant increase in illegal crossings, with over 7 million arrests since 2021. Harris previously emphasized environmental issues over immigration in her political career, and many Republicans point to her past advocacy for more lenient immigration policies as part of the problem. Additionally, Republican lawmakers, such as Sen. JD Vance and Rep. Darrell Issa, have invited Harris to witness the border situation firsthand, highlighting their belief that the administration's policies have effectively created an open border. Despite the backlash, some media outlets and Democratic officials have defended Harris, asserting that she has been unfairly criticized for her role. The ongoing debate centers around the effectiveness and consequences of the Biden-Harris immigration policies amid a rising migrant crisis.
