A public spat has broken out among Republicans over a new Israel deal, with a GOP figure blasting JD Vance's defense of it.

• Vice President JD Vance defended a deal involving Israel and pushed back hard on its critics, which surprised even allies.
• Republican Randy Fine called Vance's comments "inappropriate" and "disgusting."
• Fine argued Israel was built by Jewish people after the Holocaust, not created or funded by the United States.
• He pointed to past US arms embargoes on Israel and told Vance to brush up on his history.

Outlook: Expect the Republican infighting over US support for Israel and this deal to keep spilling into public view.
