US authorities ‘seeing large numbers of migrants at border’ before Title 42 expiration – as it happened

Homeland security secretary Alejandro Mayorkas warns people against crossing border illegally in White House briefing

We're a few minutes away from the daily White House press briefing, where homeland security secretary Alejandro Mayorkas will appear ahead of the midnight expiration of Title 42, the rule put in place under Donald Trump that has allowed US authorities to turn away most asylum seekers over the past three years.

Immigration authorities and some communities at the border are bracing for a potential surge of new migrants once the measure expires, and Mayorkas is likely to use his appearance to warn people against trying to cross into the US illegally, and outline steps Washington will take to stem the flow. He may also be asked about the possibility Republicans will follow through on their threats to impeach him over the situation at the border.
