Donald Trump is undoubtedly responsible for an exceptionally inhumane migration policy.

But he did not invent all the horrors that he enforced.

The recordings were already four years old at the time.

They showed children in cages, yes - but Trump wasn't President when this happened.

But Barack Obama.

With Joe Biden as runner-up.

In fact, Obama was nicknamed "Deporter-in-chief". Over three million people were deported under him, more than ever before. Migration expert Doris Meissner, during the administration of Bill Clinton, commissioner of the then immigration authority INS, explains Obama's calculation: "He wanted to show Congress that he was serious about enforcing immigration regulations."
