Five Democratic senators introduced a non-binding resolution on Thursday denouncing Israeli Prime Minister Benjamin Netanyahu’s campaign promise to annex parts of the West Bank.

Two of them, Sens. Bernie Sanders (I-Vt.) and Elizabeth Warren (D-Mass.), are running for the Democratic nomination for president in the 2020 election.

“Unilateral annexation of portions of the West Bank would jeopardize prospects for a two-state solution, harm Israel’s relationship with its Arab neighbors, threaten Israel’s Jewish and democratic identity, and undermine Israel’s security,” stated the resolution.

It mentioned that “the policy of the United States should be to preserve conditions conducive to a negotiated two-state solution.”

The other senators who introduced the measure were Jeff Merkley (D-Wash.), Dick Durbin (D-Ill.), Tammy Duckworth (D-Ill.) and Dianne Feinstein (D-Calif.).
