U.S. President Joe Biden and likely Republican challenger Donald Trump made duelling trips to the U.S.-Mexico border in Texas on February 29, highlighting the importance of immigration as an election issue for the 2024 election. Biden chose the Rio Grande Valley city of Brownsville, where illegal crossings have dropped sharply, to focus on Republican obstruction of a bipartisan border security deal. Trump, on the other hand, visited Eagle Pass, the corridor currently seeing the largest number of crossings, to criticize Biden’s handling of the border.
