The White House is not considering putting aid to Ukraine in a separate bill, and the Republicans are working on a backup plan.

The White House is not discussing the possibility of creating a separate bill on aid to Ukraine and Israel, spokeswoman Karin Jean-Pierre said. At the same time, the Pentagon believes in bipartisan support for Ukraine.

“It’s a matter of moving forward, and active negotiations are ongoing,” Pentagon spokesman John Kirby added.

According to Bloomberg, key Republican senators are considering the possibility of supporting a $106B military aid package for Ukraine, Israel, and Taiwan that is not tied to border policy changes, as the conclusion of a bipartisan agreement in the Senate is in question.

Presumptive Republican presidential nominee Donald Trump, House Speaker Mike Johnson, and other conservatives oppose the border deal. The situation prompts consideration of plan B. But a separate aid package for Ukraine will also likely provoke opposition from radical Republicans.
