What are the key criticisms of the Biden administration's handling of Haitian migrants at the U.S.-Mexico border?

John Oliver highlights several concerning aspects of the Biden administration's response to Haitian migrants at the Del Rio, Texas border crossing. The most shocking was the treatment by border patrol agents on horseback who appeared to use horse reins like whips against migrants, with one agent making derogatory comments about Haiti. Oliver criticizes the stark disconnect between the administration's public statements and the harsh reality migrants face. He points out the irony that America's first impression on these asylum seekers involves "a belligerent man dressed as a party city park ranger screaming at them on horseback," which damages America's international reputation. The broader critique extends to immigration policy inconsistencies, particularly the continued use of Title 42 - a Trump-era policy for expelling asylum seekers under public health pretenses.
