Forty-seven progressive House Democrats, led by Rep. Ro Khanna (D-CA), signed onto a letter to President Donald Trump and Secretary of State Marco Rubio calling for the U.S. to recognize a Palestinian state on the heels of similar decisions by European allies last week.

“It has long been acknowledged by much of the international community and previous U.S. administrations of both major political parties that a Palestinian state recognized as a full and equal member of the community of nations is necessary to fulfill the legitimate national rights of the Palestinian people and ensure the state of Israel’s survival as the democratic homeland of the Jewish people,” the letter, which was first reported on by Jewish Insider, reads.

The lawmakers argue that because the current Israeli government opposes a two-state solution — a position currently shared by much of Israeli society — and is “actively undermin[ing]” the prospects of an independent Palestinian state, “meaningful action is necessary to join the majority of the world in codifying Palestinian statehood and to unlock the potential for a broader regional peace and security arrangement.”

Trump vowed last week week that he would not allow Israel to annex the West Bank.

The letter also claims that recognizing Palestinian statehood would make reform of the Palestinian Authority “far more achievable and sustainable.”

Signatories to the letter include Reps. Becca Balint (D-VT), Donald Beyer (D-VA), André Carson (D-IN), Greg Casar (D-TX), Joaquin Castro (D-TX), Judy Chu (D-CA), Danny Davis (D-IL), Madeleine Dean (D-PA), Diana DeGette (D-CO), Chris Deluzio (D-PA), Mark DeSaulnier (D-CA), Maxine Dexter (D-OR), Lloyd Doggett (D-TX), Veronica Escobar (D-TX), Dwight Evans (D-PA), Bill Foster (D-MA), Maxwell Frost (D-FL), John Garamendi (D-CA), Chuy García (D-IL), Sylvia Garcia (D-TX), Robert Garcia (D-CA), Al Green (D-TX), Val Hoyle (D-OR), Jared Huffman (D-CA), Jonathan Jackson (D-IL), Sara Jacobs (D-CA), Pramila Jayapal (D-WA), Hank Johnson (D-GA), Marcy Kaptur (D-OH), Zoe Lofgren (D-CA), Stephen Lynch (D-MA), Betty McCollum (D-MN), James McGovern (D-CA), Chellie Pingree (D-ME), Mark Pocan (D-WI), Mike Quigley (D-IL), Emily Randall (D-WA), Mary Gay Scanlon (D-PA), Jan Schakowsky (D-IL), Bennie Thompson (D-MS), Mike Thompson (D-CA), Jill Tokuda (D-HI), Paul Tonko (D-NY), Nydia Velázquez (D-NY), Maxine Waters (D-CA) and Bonnie Watson Coleman (D-NJ).

Dexter and Garcia were both beneficiaries of significant outside spending from AIPAC’s United Democracy Project super PAC in their primary races, running against farther-left anti-Israel opponents.

Balint and Schakowsky are both Jewish. Davis, Evans and Schakowsky are retiring from Congress at the end of their current terms.

Many of the furthest-left lawmakers in the House, including some of the Jewish state’s most outspoken critics, did not sign onto Khanna’s letter, nor did some of the more moderate Democrats backing a concurrent effort to place strict restrictions on U.S. aid to Israel.

The letter is backed by groups including American Muslims for Palestine, DAWN, Emgage Action, Indivisible, J Street, MoveOn, MPower, Muslim Public Affairs Council, New Jewish Narrative and the Quincy Institute.

There is a notable split on this issue within the Democratic caucus: Khanna’s letter follows a letter from 30 moderate pro-Israel Democrats condemning unilateral recognition of a Palestinian state as “performative” and saying that doing so risks “emboldening Hamas, entrenching division, and undermining the very legitimacy and peace such recognition purports to advance.”
