WASHINGTON – After months of declining to explicitly endorse the Taylor Force Act, AIPAC announced on Wednesday their support of the bipartisan legislation that would cut off U.S. economic assistance to the Palestinian Authority (PA) until they cease payments to families of terrorists.

“We urge all members of the committee to work together to move this important legislation forward and to VOTE YES to report the bill from committee,” Brad Gordon and Marvin Feuer, AIPAC’s Directors on Policy and Government Affairs, wrote in a letter to members of the Senate Foreign Relations Committee. “We are hopeful that the Senate Foreign Relations Committee markup will produce a strong, bipartisan bill that will send a very clear message to the Palestinian Authority: Stop these payments to terrorists and their families or your assistance will be cut.”

The Senate Foreign Relations Committee will vote on the bill on Thursday morning.

AIPAC appears to be persuaded by the revised version of the bill released on Tuesday. The updated version allows continued payments towards Palestinian humanitarian programs and also contains an exemption for the East Jerusalem Hospital Network. “The Taylor Force Act does not affect U.S. funding for security cooperation, nor does it cut humanitarian programs,” AIPAC noted. Unlike the Jerusalem Embassy Act, this legislation does not contain a waiver allowing the president to delay implementation of the funding cut.

The bill had no Democratic backing when it was first introduced by Senator Lindsey Graham (R-SC) in February. Senator Joe Manchin (D-WV) signed on as a co-sponsor of the legislation in June. However, despite the bipartisan support, AIPAC remained unwilling to actively lobby for the bill. “We strongly support the legislation’s goals and we are working with Congress to build broad bipartisan support that will require the Palestinian leadership to end these abhorrent payments,” AIPAC spokesman Marshall Wittmann told Jewish Insider at the time.

On Monday, Senator Bob Corker, Chairman of the Senate Foreign Relations Committee, announced a deal was reached with members of the committee to advance the legislation. “This is yet another sign of the bipartisan commitment in Congress to the security of Israel and to ending the Palestinian Authority’s outrageous incitement to violence against Israelis,” the conference of Presidents of Major American Jewish Organizations said in a statement.

The House version of the bill, introduced by Doug Lamborn (R-CO), has increased substantially the number of co-sponsors to 100, but without any Democratic support.

“For too long, some supporters of Israel have feared cutting funding to the PA because it would ‘destabilize’ a supposed peace partner. Now, hopefully, [they] all understand that continuing to fund the PA while it funds murder legitimizes their policy and keeps peace further away,” Eugene Kontorovich, Professor of Law at Northwestern University, told Jewish Insider. “The Palestinian government’s salaries for convicted terrorists is not just a reward for murder, it is murder-for-hire.”

Noah Pollak, an advocate in favor of the Taylor Force Act, said that AIPAC’s formal backing is a “welcome development and something we have been encouraging for many months. We hope that AIPAC will now put its considerable resources behind promoting the bill, even if it is not possible to earn a perfectly equal number of Republican and Democratic votes. We have worked hard to gain bipartisan support. But in the end, passage of a strong, meaningful bill is more important than the details of the vote count.”

In a statement emailed to Jewish Insider, the Republican Jewish Coalition (RJC) applauded AIPAC’s support  and expressed hope that “Democrats will step up, join in, and support a strong and effective version of the bill without diluting it with amendments.”

When informed of AIPAC’s support of the bill, Senator Marco Rubio (R-FL) said the decision was helpful. While AIPAC’s view on the Taylor Force Act isn’t conditional for Rubio, the pro-Israel organization’s position “is influential with me,” he added.

“Once this bill became bipartisan, it became easier for a wider range of groups to support it,” Jonathan Schanzer, Senior Vice President at the Foundations for the Defense of Democracies (FDD), explained. “It’s also important to see that the bill ensures continued security assistance to the PA, as well as humanitarian assistance to Palestinians in need. In short, the politics in Washington have made this easier to back, and the bill itself does not ignore the importance of stability.”
