Tier 3, “Pro-Israel, critical”
Lead sponsor of the Ceasefire Compliance Act, which would bar US-origin weapons from end use in Gaza/the West Bank if Israel violates the Oct 2025 ceasefire, blocks humanitarian aid, resumes bombardment, annexes the West Bank, or fails to curb settler violence — but it exempts Iron Dome/David's Sling/Arrow 3, carries a presidential 'vital to the national security' waiver, and sunsets after five years. Voted for the April 2024 aid package; no 'genocide' usage. He frames the act as setting “clear enforcement mechanisms, transparency, and consequences”; the ‘blank check’ line in the same release is J Street president Jeremy Ben-Ami’s, not his. FEC records show a single $2,000 DMFI contribution in 2022 plus $37,492 of DMFI independent expenditure supporting him that same cycle, and no AIPAC money. In 2024 and 2025 he signed letters urging the State Department to affirm U.S. opposition to the forced displacement of Palestinians from Gaza (January 2024), backing refugee status for Gazans who are close relatives of U.S. citizens and permanent residents (June 2024), demanding answers on the detention of the student activists Mahmoud Khalil and Mohsen Mahdawi (March and April 2025) and urging Secretary Rubio to demand that Israel “immediately facilitate a massive surge of humanitarian aid” into Gaza, infant formula included (August 2025). In October 2024 he co-led, with Rosa DeLauro and Senators Chris Van Hollen and Dick Durbin, a letter of 88 lawmakers urging President Biden to sanction Israeli ministers Smotrich and Ben-Gvir over incitement of settler violence. With most House Democrats he signed the September 2025 Schneider–Raskin letter opposing annexation of the West Bank, and in January 2026 the Welch–Khanna letter urging Secretary Rubio to warn Israel off annexation and the E-1 settlement and to reimpose Biden-era West Bank sanctions. In September 2026 Casten signed the Dexter–Ruiz letter seeking the release of Gaza pediatrician Dr. Hussam Abu Safiya from Israeli detention without charge (Sep 8) and a 72-member letter urging Netanyahu to contain settler violence in the West Bank and “halt further settlement approvals” (Sep 24). On Oct 1, 2026 Casten became an original cosponsor of the Stop the Settlements Act (H.R.10642), which would sanction those who build or expand Israeli settlements in the West Bank and Gaza and ban imports of settlement goods. In a Shaw Local candidate questionnaire published Sep 23, 2026 he wrote, “I have always supported the provision of defensive weapons to Israel,” but “I have sometimes, but not always, supported the provision of offensive weapons to Israel,” citing his vote against one post–October 7 package “because that funding package failed to include humanitarian aid to protect the people of Gaza.” In February 2024, on a J Street delegation with five other House Democrats, he went to Khirbet Zanuta, which their joint statement calls “a Palestinian village in the West Bank where settlers destroyed homes and a school.” In February 2026 he and Rosa DeLauro led a J Street delegation through the Jordan Valley and east of Ramallah, driving through the ruined remains of Ras ‘Ein al-‘Auja, whose residents had fled settler violence weeks before, and visiting Fasa’il al-Wusta; in a May 2026 op-ed they wrote that two weeks later the Israeli military “demolished the home of the family we visited,” and that “annexation of the West Bank is happening before our very eyes.” In June 2026 Casten signed a letter to Secretary of State Marco Rubio, led by Reps. Becca Balint and Joaquin Castro, on Israel’s operations in southern Lebanon, saying Israel’s “targeted, mass destruction of civilian homes and infrastructure does not constitute Israeli self-defense” and asking that, if U.S.-origin arms were confirmed in those operations, the administration “stop arms transfers being used in these operations until these violations cease”; the letter also affirmed that “Israel has a right to defend itself.”
A 3. He wrote the Ceasefire Compliance Act (H.R.7645), which would bar U.S. weapons from use in Gaza and the West Bank if Israel breaks the ceasefire, blocks humanitarian aid, annexes the West Bank or fails to curb settler violence: his main step toward limiting weapons. In May 2024 he also signed the Crow–Deluzio letter of 88 House members urging President Biden to weigh tools “from refreshing the assurances to withholding specific arms transfers” while Israel restricted aid into Gaza. He is not among Block the Bombs’ 82 cosponsors, and on July 15, 2026 he voted No on the Massie amendment, keeping Israel’s $3.3 billion in military financing. He signed the April 2024 letter urging Speaker Johnson to bring the Senate’s national-security package, with its aid to Israel, to “an immediate vote,” and voted for the April 2024 aid package, the “river to the sea” resolution and the Hamas-financing bill (H.R.340); his own bill exempts Iron Dome, David’s Sling and Arrow 3; and he has not used the word genocide. He writes that he has “always supported the provision of defensive weapons to Israel” and “sometimes, but not always” offensive ones. Brad Lander, who names the genocide and would vote for no more aid, is a 3/4. Counter-case: 3/4, since writing a bill to limit weapons is a stronger act than cosponsoring one, he co-led the October 2024 letter urging sanctions on Israeli ministers Smotrich and Ben-Gvir, and he voted against the IHRA bill, both ICC-sanctions bills and the 2026 anti-boycott bill.
