As I recall reading, this power was applied during the pandemic, when there was a demonstrable “deriment”. Afterwards, the cours might rule that the specific detrimnet no longer exists. I imagine Biden could claim the high volume itself is sufficient detriment, depnding on what the courts say about that claim.
The bit about the majority claiming asylum at the border was IIRC from a NYTimes article a while ago. (The article also pointed out that while a decade or two ago it was mexicans, most now are from points further south and from all over the world) That’s why there are people camped out at the bridges and across the river from entry points, waiting for a turn to claim asylum. Of course, some people still try illegal crossings.
What is affirmative asylum?
An affirmative asylum seeker submits an asylum application to the Department of Homeland Security after entering the country. In this case, they proactively seek asylum status.
What is defensive asylum?
A defensive asylum seeker requests asylum as a defense against deportation during a standard removal proceeding. This means they are already being deported when they claim asylum to stay in the US.
I find this bit; a Border Patrol summary for one week…
Asylum seekers are again opting to turn themselves in to Border Patrol despite the Biden administration’s “carrot and stick” approach of legal pathways and harsh limits on asylum access. Shelters and migrant routes are similarly full throughout Mexico.
indications are some cross illegally but then go “seek out” CBP to claim asylum.
