Some Congressional Republicans are already wary about a deal made behind closed doors that would shut down the border if crossings reached a certain level of illegal immigrants.

Lawmakers in the Senate established a deal on Friday that they intend to release in the next few days that would give President Joe Biden a new expulsion authority if the migrant encounters exceeded 4,000 a day over a one-week period. However, the specific details of the law have not been released, and some Republicans appear skeptical of the deal as a whole.
