A public fight has broken out inside the pro-Trump world over an American-born commentator living in Israel who has been attacking Vice President JD Vance, and it is bad news for the pro-Israel lobby's standing on the American right.

• Trump allies now say Emily Schrader is running a foreign influence campaign aimed at Vance, and they want her funding disclosed.
• The fight started over Iran: Schrader has ripped Vance for backing a deal that lets Iran get money to rebuild.
• She is paid by Israeli outlets that have taken money from the Israeli government, including its ministries handling public messaging abroad.
• Republicans also point out she praised Kamala Harris and Hillary Clinton before positioning herself as a conservative.
• Schrader has sent legal threat letters to critics, which has only made the story bigger.

Outlook: Expect the split on the right over Israel and Iran policy to widen, with more pressure to force pro-Israel media figures to disclose who pays them.
