The US has ended Covid-19 border restrictions that blocked many migrants at the border with Mexico, immediately replacing the Title 42 restrictions with sweeping new asylum rules meant to deter illegal crossings.

What is Title 42? In March 2020, under Donald Trump, the CDC issued an order limiting migration into the US, saying it was necessary to reduce the spread of Covid. The order made use of little-used laws dating back more than a century that authorized border officials to immediately remove migrants, including people seeking asylum, overriding their normal rights. Migrant and human rights advocates condemned Title 42 as a ploy to stop immigration. The Biden administration said it wanted to end Title 42 - but in fact tightened restrictions further.

What's next for migrants to the US? Starting on 12 May, asylum seekers will be allowed to request asylum again at the border and will be interviewed by immigration officers. Those who are found to have a credible fear" of being persecuted in their home countries can stay in the US and go through the immigration court system until a final determination is made. That can take years.

On an internal call, Licht reportedly told staffers: You do not have to like the former president's answers, but you can't say that we didn't get them. Kaitlan pressed him again and again and made news ... Made a lot of news, [and] that is our job."
