How did border apprehensions change after the Trump administration took office?

Border apprehensions along the U.S.-Mexico border plummeted by approximately one-third in January, with nearly 35,000 fewer apprehensions compared to December. This significant drop coincided with the change in leadership to the Trump administration, which made immigration one of its primary focuses following the election. The decline became even more pronounced after President Trump officially took office on January 20. While seasonal factors like cold weather might contribute to fewer border crossings in winter months, the timing and scale of the decrease strongly suggest that the Trump administration's immigration stance and policy shifts played a substantial role in reducing unauthorized border crossings.
