FILE - Venezuelan migrants walk across the Rio Bravo towards the United States border to surrender to the border patrol, from Ciudad Juarez, Mexico, Oct. 13, 2022. President Joe Biden last week invoked a Trump-era rule known as Title 42, which Biden's own Justice Department is fighting in court, to deny Venezuelans fleeing their crisis-torn country the chance to request asylum at the border. The rule, first invoked by Trump in 2020, uses emergency public health authority to allow the United States to keep migrants from seeking asylum at the border, based on the need to help prevent the spread of COVID-19.
