"Biden Threatens Border Shutdown Over Senate Immigration Bill"

President Biden vows to "shut down the border" the day he signs the Senate immigration bill, which includes new limits on asylum and an expulsion power for rapidly returning migrants to Mexico if encounters surpass certain thresholds. The bill aims to resolve asylum claims in six months without detaining migrants and includes provisions for additional border patrol agents, immigration judges, asylum officers, and inspection machines. Biden urges Congress to provide the funding he requested in October to secure the border, while facing mounting Republican opposition and criticism.
