A conservative outlet has reported that people close to Trump believe a US-born Israeli commentator is running a foreign influence operation against Vice President JD Vance, a sign of a widening Republican split over Israel and Iran.

• Trump allies say Emily Schrader, who lives in Israel and works for Israeli-linked outlets, is attacking Vance as part of a foreign campaign, not organic criticism.
• Her anger centers on the Trump administration's Iran deal and Vance's talk of letting Iran rebuild if it keeps its side of the bargain.
• One outlet she works for was reported to have drawn most of its funding from the Israeli government, and took Israeli money again for public-relations videos after the Gaza war started.
• She publicly announced joining a group of Israeli tech and intelligence veterans working with Iranian operatives, then objected to being described that way.
• Republicans calling her a "leftist" point to her past praise for Biden, Harris, and Clinton.

Outlook: Expect more Republican infighting over Israel's influence in Washington as the Iran deal moves forward, with legal threats and accusations of foreign interference flying in both directions.
