White House expected to unveil sweeping immigration order

President Joe Biden is expected to issue a sweeping new executive order aimed at curbing migrant arrivals at the US-Mexico border as early as Tuesday.

Under the planned order, US officials could swiftly deport migrants who enter the US illegally without processing their asylum requests once a daily threshold is met, according to CBS.

That, in turn, will allow border officials to limit the amount of migrant arrivals, three unnamed sources briefed on the expected order told CBS, the BBC's news partner.

More than 6.4 million migrants have been stopped crossing into the US illegally during Joe Biden's administration - a record high that has left him politically vulnerable as he campaigns for re-election.

Migrant arrivals have plummeted this year, however, although experts believe the trend is not likely to be sustainable.
