What is John Oliver's main criticism of the Biden administration's immigration policy approach?

John Oliver criticizes the Biden administration for creating a significant disconnect between their stated values and their actual immigration policies. He specifically highlights how the administration continues using Title 42, a Trump-era policy that allows expelling migrants under public health pretexts, while simultaneously projecting humanitarian rhetoric. Oliver's critique centers on the treatment of Haitian migrants at the southern border, particularly referencing disturbing images of border patrol agents on horseback. He argues that the administration is failing vulnerable populations by sending them back into dangerous situations. The host emphasizes that empty promises and moral posturing are insufficient - the administration must demonstrate their commitment through concrete policy changes rather than just telling people about their values.
