Tension continues to mount on Capitol Hill as the Senate pushes negotiations for a bipartisan border enforcement deal attached to military aid for Ukraine. Far-right Republicans, encouraged by former President Trump, have said they’ll sabotage the deal even though it includes some of the harshest immigration restrictions yet, including granting executive authority to block people from applying for asylum once the number of apprehended migrants at the U.S.-Mexico border reaches a daily average of 5,000 in a week. President Biden has already vowed to use the new emergency authorities to “shut down” the southern border, praising the deal as “the toughest and fairest set of reforms to secure the border we’ve ever had in our country.”

Immigration rights groups have condemned the deal, urging Biden to support humanitarian relief. The proposal also drew criticism from Mexican President Andrés Manuel López Obrador.

President Andrés Manuel López Obrador: “Well, that’s not realistic, with all due respect. How are we going to solve the migration problems with walls? How are we going to solve migration problems by closing the border? Why these proposals? Because elections are coming.”
