US President Joe Biden speaks with a member of the US Border Patrol as they walk along the US-Mexico border fence in El Paso, Texas, on January 8, 2023.
CBP tracks hundreds of thousands of migrant encounters at the U.S.-Mexico Border every month, but that stat does not include the number of known "gotaways," or migrants who were detected by authorities but not apprehended. Since Biden entered office in January 2021, border crossings have exploded, and at least 1.2 million migrants successfully evaded authorities.
The first half of Biden's four-year term saw monthly border encounters rise from 101,000 in February 2021 to 251,000 in December 2022, according to CBP stats.
