EAGLE PASS, Texas (Reuters) - Beneath a blazing sun, a record number of migrants seeking to enter the United States are crossing the Mexican border. Some wade or swim through the waters of the Rio Grande into Texas. Smugglers ferry groups of others on rafts.

U.S. President Joe Biden, a Democrat, promised a more humane border policy than that of his Republican predecessor Donald Trump, but the increase in numbers has challenged U.S. law enforcement and drawn criticism from both political parties.
